Recently, people on an infamous detrans extremist subreddit have become threatened by the very existence of the 1st Amendment of the Constitution, which protects freedom of speech in the United States:

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
1st Amendment of the Constitution of the United States

It all began when Julia Mason MD sent a post on /r/detrans looking for another detrans extremists to speak at New York Times article:

I'm of two minds posting this. On the one hand, there's an opportunity for the stories of detransitioners to be shared in the friggin' New York Times, which could reach a lot of people who currently believe the detransition rate is "less than 1%." I'm working hard to turn my profession around, I've gotten the AAP to at least say they're going to do a systematic review of the evidence, but to really change things we need to change the culture. Sharing stories of detransition in the New York Times is a way to work on changing the culture, at least in the United States.

On the other hand, losing your anonymity is a BFD. It depends on your location and on your life circumstance. If you work for Kaiser, for example, I would say no: don't come forward. I am able to speak out on this topic (despite living in Portland Oregon) because I work for a small independently owned private practice and my boss agrees with me about pediatric gender transition.

When we scroll the page to see comments, we will see people being afraid of ending up on Andrea James' Transgender Map, despite the people having any right to criticize other people:

Andrea James is a trans woman who runs a website called Transgender Map, which, to my knowledge, mostly serves as an information hub for all things gender and gender-affirming care. She's also created web pages on people she doesn't like, namely detransitioners or members of the GC movement. If there's any real life info on folks, she'll include it in their pages, no matter how questionable it might be (like borderline doxxing people). Here's a link that features many of us if you'd like to peruse:

If you end up on this page, it's usually not for a good reason. It means more eyes on you and that now you have someone who's willing to find details about your life you had no idea were out there and compile them so people who hate you can easily find them.

Unlike Kiwi Farms, which was for a while the world's largest doxxing forum, the amount of real-life information on her pages is absolutely nil. In comparison, while the users of this forum who are ready to go great lengths at collecting information on their targets and use this information against them, the information that's on the Transgender Map's website is publicly available.

What it can be concluded is that detransitioners want the right to free speech to apply only for them, despite the near-zero harm done by aggregating publicly-available information in one place.
