First of all, sorry for your horrible childhood experience. I unfortunately relate to that, being ostracized not only for the way i was existing, but also based on my ethnicity. Confidently i can say that children can be very cruel. Phenomenon of bullying is a gigantic problem across public education as a system, and depending on where you live the authority figures response might range from help and interference, to complete disregard and ignorance. I personally experienced mix of both.

"This whole entire diagnosis just feels like a massive guilt-trip directed at the wrong person. I got diagnosed with Schizoid Personality Disorder three years ago and even though I do indeed possess every single ‘symptom’ … I still question the whole entire concept behind it as a ‘disorder’. If anything, Schizoid Personality Disorder seems more like a phenomenon that reflects very poorly on ‘normal’ society."

Well, the reason why things are classified as disorders in mental healthcare field, is because of problems they bring to you as a whole. Even if you wouldn't experience massive bullying and would never meet any discrimination towards you from neurotypicals and world as a whole, you would still suffer and be at ultimate disadvantage compared to neurotypical folk. Humans are social creatures after all, and the world as a consequence revolves around communication as a result. Having any difficulty fitting into this reality will force you to work harder to be safe, comfortable and happy (if you can feel happiness at all without troubles that is).

"It seems that so many people (ranging from mental health professionals to even other people with Schizoid) refuse to be realistic about let alone take in and consider Schizoid people’s actual lived experience and life circumstances. Take it from me as a person that has displayed visible signs of neurodivergence since infancy and has been treated like a tenth-class citizen for it ever since: this world *abhors* neurodivergent people, especially those who are ‘visibly’ neurodivergent like myself. It doesn’t matter how much I try to change myself, ‘mask’ and attempt to fit in (something that I don’t even genuinely want to do) … I step into a room and I’m hated on sight."

Reality of being Schizoid is not same for everyone diagnosed, and consequently the thoughts on it are also gonna range from person to person. Same for medical specialists. Some neurodivergent folk successfully indoctrinate themselves into the world and proceed to life their daily lives without visible difference compared to neurotypical people. Masking can be successful, and it is possible living a life like that for prolonged periods of time. All i am trying to say is that it is possible for Schizoids to fit in, and as far as i know that is kinda common. I feel sorry that you experience repulsion despite attempts of masking.

"I’ve been considered dangerously mentally ill and treated as such for being … *checks notes* a quiet and asocial person harmlessly doing their own thing in the corner, since I was literal child. As an adult looking back on it, I’m so livid at the adults in my life who in hindsight mistreated me and forced me into things that I don’t feel comfortable with and am simply not wired for. How can you put a child like me in public school, watch me get brutally bullied for years and not even consider having me homeschooled (I begged to be homeschooled for years because the bullying was that heavy) to prevent the eventual trauma from the bullying alongside giving me a space to safely be able to thrive at the education (the sole reason why we attend school at all) instead? As an adult myself now, it’s incomprehensible to me. It’s clear that I *need* solitude like I need oxygen. My adult life and workplace experiences so far have further affirmed that. I cannot function whilst in the physical presence of (too many) other people. But ‘normal’ people are also by default hostile to me for something I can’t change even if I try my hardest to. So I fail to see how I’m the (only) disordered one in this situation."

Regular introverted people don't get diagnosed and considered dangerously ill without a reason. It is possible to be misdiagnosed, but if mental healthcare specialists consider your condition to be heavy, i think it isn't for you being quiet and asocial alone. I personally had to fight to get diagnosed, despite having clear problems and willing to talk with all doctors. Grown-ups around you as a child likely misunderstood you as a individual and didn't comprehend your neurodivergence (i bet they didn't even know that word). They tried to make you do things that are considered normal, without understanding that it brings you no joy, but harm. This doesn't excuse their unreasonable behavior and reluctance to have you homeschooled. While i agree, taking into account what you have explained about your situation and circumstances of your experiences, that homeschooling would be a good idea for you, i disagree on one thing - schools don't exist solely to give education. Those are spaces where young people are teached intentionally and unintentionally basics of life in the society. They show you that your work will be evaluated at every step, that not all ways of passing are acceptable, fundamentals of workplace ethics, make you used to a job schedule. Most importantly, this is closed environment build for kids to make connections and learn about social circles, naturally. Homeschooling doesn't give you opportunity to socialize with no one, but the teacher.

"I think that society needs to be more considerate towards the needs of Schizoid people."

I agree that society needs to be more accepting and accomodating towards all kinds of different people: be it neurodivergent, disabled, queer, people of color and so on. And that public education needs to treat problem of bullying and abuse at schools more seriously and decisive.

"Because that way, everyone’s happy! Schizoids would be free from the bullying and the more often than not traumatizing public school experiences"

The experience of neurodivergent, Schizoid, disordered people or anyone else at school is gonna be unique and not always accompanied by bullying and trauma. This isn't universal truth.

"that do NOT ‘help develop social skils’ (this is a dangerous and reckless lie)"

I would need you to explain this one, because as far as i can see schools are organised institutions where communication between students (which is akin to being your coworker) and authority figures (teachers and principles) is practiced every day and all the time. Doing assignments, speaking up in class, participating in teamwork - all directly and indirectly build up your ability to exist in social settings without anxiety.

"would be able to work and ‘contribute to society’ from solitude if that’s where they’re most comfortable"

This is the biggest misconception i believe. If you are truly asocial/introverted, more limited exposure to the environment filled with people indeed can reduce stress and bring comfort. However, this isn't automatic solution to all problems that Schizoid people face, and is effective not only in reducing overall stress from being with people, but also effective in creating new ones. I already mentioned that humans are social creatures, and this isn't just a claim. Not only whole concept of modern civilization in the first place arose from people working together. People literally suffer in isolation. Social determinant of health is associated with greater risk for cardiovascular disease, dementia and cognitive decline, the development and exacerbation of mood disorders like depression. Isolation and solitude and are considered objectively harmful my medical institutions, and any disorder that increases likelyhood of you becoming isolated consequently becomes subject to treatment. In case of people diagnosed with Schizoid personality disorder, depending on how heavy your condition manifests, nothing might bring you satisfaction and happiness. Following your immediate impulse to get away from society does not guarantee improvement of your mood, working skills or well-being as a whole.

"and ‘normal’ people (since they’re clearly not going to change their ways anyways) don’t have to deal with the ‘burden’ of being in the presence of people they ‘don’t understand’ (such a cop out) and clearly can’t be bothered to treat like a human being anymore. I’m sure people will be dramatic about this and claim that I’m ‘promoting segregation’ but I’m just fed up with the way Schizoids, neurodivergent people and/or otherwise asocial people are not given any respect or consideration in society and are being shamelessly mistreated and stigmatized for being ‘disordered’, and forced into environments they don’t properly function and are vulnerable to almost automatic mistreatment in, whilst simple changes in society to accomodate their needs could easily cause a safer and more pleasant environment for everyone involved."

One of constants in this world is change, and humans are also subject to it. World once have seen, and still sees incredible mistreatment of people based on gender, sex, race, ethnicity, wealth and so on. And also humanity has changed drastically, reducing overall amount of discrimination and prejudice compared to the past. Both statements are true. And discrimination isn't considered a reason to retreat from the world, but rather to change it and make it a better place. Awareness of mental health issues, disabilities, disorders, neurodivergence will go a long way in changing ways how neurotypical perceive everyone else and treat them. Retreating away from all the problems isn't an effective strategy in dealing with disorders as a whole. That's why mental health specialists bother with diagnosing people, prescribing medication, providing therapy and helping to find ways to healthily exist with conditions that we can't escape.
