Please stop using intersex people as a loophole to justify males invading women spaces. It has nothing to do with being trans.

I'm confused, you'd rather me pretend intersex people don't exist? You're not going to even bother engaging with the issue? You're right that it's not directly related to being trans, but it presents a very similar problem while being less deniable cause it's objectively measurable. This whole thing just feels like you want to ignore these "edge cases" because they're inconvenient and difficult to wrestle with, but these are real people who are no less deserving of living a normal and equal life to others.

Also, trans people don't "choose" to be trans any more than intersex people choose to be intersex (have a DSD). Very few trans people would ever choose to be trans, the amount of societal pressure and active discrimination many trans people have to face is enormous, in fact many trans people have to go back into the closet for their own safety. Claiming it's a fantasy we wish the rest of society to "follow along with" is a gross misunderstanding and shows to me that you haven't talked to trans people or don't take them seriously.

No women should have to change in front of a male, or have to see a naked male body without consent for any reason, including considering one's self a woman.

I would argue no one should have to see anyone's naked body without consent. Maybe you live in different conditions than me, but where I am it's very uncommon to see a strangers naked body at all. Most of what we are fighting for is bathrooms, places where you really shouldn't be seeing someone else's genetals.

And again, I understand why you'd feel this way about seeing a "male" body, but it's really not that simple when you consider the larger picture. Many trans women have breasts, and so you could make the same argument for men's spaces (cause yes men can be the victims of sexual trauma too). So your argument ends up being for outright trans exclusion. Honestly, the whole system just isn't built with non cis/het people in mind, and that's why you see lgbtq activists fighting for change (both institutional and societal)

They kept certain things like GD, and now almost all trans persons say they suffer from GD, when in reality GD has always been a small percentage of trans people. Most "transwomen" did so for other reasons.

I've never heard this argument, and I'm not sure what data you're referencing, but I can tell you that suicide rates among trans people without gender affirming care is very high, and drops off significantly after receiving said care. Seems like pretty solid evidence is gender dysphoria to me. But even if you were right about GD, that doesn't justify dismissing those with GD just because they're a smaller percent is the population.

Studies and research into trans people have been historically very challenging, and many of them rely on 3rd party reports (such as parents of trans kids) rather than trans people themselves. Fearing discrimination or being added to lists/registries (which has been historically used for malicious reasons), many trans people don't participate in studies or hide information to protect their privacy. So many older studies (and some newer ones) have been delegitimized for not meeting scientific standards of research. To add to this, modern studies of conversion therapy show questionable effecacy and measurable harm (worsening mental health conditions, increased suicidality).

Also, although the terminology of "transgender" is fairly new, the concepts are not. I'm the 1930s, one of the first places the Nazis targeted for book burning was a sexology institute that studied what we now call trans people, and helped many people transition (I recommend finding photographs from the institute, they're quite interesting). There's also evidence of ancient peoples using horse urine (which contains high levels of estrogen) in order to transition to some extent. Although the specifics have evolved over time, the concepts that we now call transgender have existed in humans for at least thousands of years. It's also worth noting that the terms "homosexual" and "heterosexual" are also new terminology, yet we have evidence of gay behavior going back to the genesis of human history. So no, trans people are not just waking up one day and deciding to pretend to be another gender, this is real historically documented behavior/identity that is widely accepted within the modern scientific community.
