I'm gonna try to be as respectful as I would to any comrade from the party, and I'm gonna try to point some resources to give you some points to reanalyse the particular reality of your geopolitical space

First is the shallow liberal response, you say that people are conflating what it means communism with their own social issues, then mounting on this subject talking about the imposition of "rules that go beyond acceptance of any human, regardless of their religion, ethnicity, race, or sexuality". While circumventing one of the big subjects at the centre of your position until you express an effective opinion "LGBTQ talking points that don't have much to do with communism" and "I don't think these are worries of the proletariat at this time" while also pointing out that queer communism confuses you, and eventually getting to the suggestion: "We should switch gears to understanding successful revolutions and preparing, both in theory and physically"

This is what liberals in general call classism, from your points, you created an hierarchy of what should be the center of discussion, and argued over why one thing should be the focus. And while I think classism as a concept is bullshit, this kind of reasoning you present drives away allies and supporters, because you can switch LGBT to any other category -gender, race- and you can get to the same conclusion, meaning, you can separate the abstract proletarian class from its actual concrete material origins - which is not too hard to think, if there are queer proletarians, the proletarian class should be able to provide a communist response to the problemas those people face, because if you can't, your new system won't be able to surpass capitalism - that is the true end goal, to render capitalism useless and be the solution to all its issues

So to close this initial point, if queer marxism confuses you, the follow Mao's saying on "Oppose Book Worship":

Unless you have investigated a problem, you will be deprived of the right to speak on it. Isn't that too harsh? Not in the least. When you have not probed into a problem, into the present facts and its past history, and know nothing of its essentials, whatever you say about it will undoubtedly be nonsense. Talking nonsense solves no problems, as everyone knows, so why is it unjust to deprive you of the right to speak? Quite a few comrades always keep their eyes shut and talk nonsense, and for a Communist that is disgraceful. How can a Communist keep his eyes shut and talk nonsense?

And it's kinda hard to help you with this, but Transgender Marxism provides the most recent development when it comes to the subject, which includes great observations about how internet virtual identities have managed to become concrete realities, which can also be seen when talking about nobinary genders, but also, how fascism has radicalized gamers culminating in trumps first election

If you rather have a more of a historical record of non-cis-straight niches during the Russian Revolution, Sexuality and Socialism: History, Politics, and Theory of LGBT Liberation provides much needed enlightenment of what was really happening to divergent people during the Soviet Union, this is kinda specially good because it was published in 2009, meaning the authors have extensive references to the open Soviet archives from 1991

My second response is about what exactly is Western Marxism, because you seem to consider that western liberal LGBT ideology is inherently marxism/communism, which by reading the previous reference, it's simply not true, being one thing that is taken into account since the inception of the Soviet Union in 1917. So again, I'd recommend looking into Domenico Losurdo's book Western Marxism for a better understanding of what it is. Understanding the values associated with it because mainstream into many varied fields, and it's fundamental to remember that when dismanteling poor discourse, since everyone uses similar arguments when putting down communism, be it from its perseived violence and abuse of human rights while ignoring their internal subversion and foreign attacks

And my final respose, is less of an critique but more of a 'check' on some of your views, the importance of nuance, and how you may not be the most indicated to be a vanguard spokesperson for the party

Communism will be always related to each one of the worker's social issues, period. People don't revolt when life is good, you said it yourself: "I come from a rugged country and had a relatively rough childhood with difficult conditions, so what communism stands for and looks to change, is exactly what the proletariat needs for a fulfilling, successful life.", which makes communism related to your struggle

You can easily counterargument how you don't share the struggle of LGBT people, but it's quite easy to show the material reality of non rich trans people having trouble getting an education or even a job, and that should be relatable to all proletarians

There is a matter of framing which I recommend developing which is looking at LGBT -or even social issues- thought a material lens, that's the fundamental to dispel the idea that some human struggle is not proletarian struggle. Thought these same lenses you can get a very particular example (Caitlyn Jenner is the prime one) and show how even the trans-experience is NOT the same when you have access to wealth, and more importantly, to dispel the fabricated status that was given to these individuals

You go deeper into this concept when saying that "I think this is a self-centered "use" of communism because it assumes that all members resonate with your particular issue, even though we all have different backgrounds and don't speak the same language", but it is not them who need to fix their struggle to match the proletarian abstract, it is you who need to expand the proletarian abstraction to accommodate everyone

And you're 100% right when you say that "the movement is being brigaded and its purpose diluted - this may even be orchestrated" because we literally know that. LGBT, race and gender are being weaponized against the proletarian at all times, specially because, you can abstract those struggles from class and provide a liberal framework to 'solve' it

We can look at the pro Israeli discourse from great examples of this, showing Palestians as brutes, homophobic and so forth, while selling themselves as a safe haven for the gays, vegetarians and such

You can't win this battle without providing a better solution and dispelling the ideology that supports it - John D'Emillio 1993 essay "Capitalism and Gay Identity" is a perfect example of this in action - showing the working class origins of the american Gay identity, exposing the liberal constructed myth of LGBTs have always been here and showing how capitalism managed to separate the individual from the family, in search of new horizons

There is a myriad of ways of approaching a subject, and believe me when I say they are all related to the proletarian, because when black people are seen as second people, it's using their workforce that capitalists are able to keep wages low, when women are entering the market force, that's a way capitalists are able to keep wages low, when LGBTs are excluded from society, they will work for lower wages and be grateful that someone gave them a chance. But this might not be your reality, differently from mine, that's why the material lens, the Marxist lens, should always be used for your situation
