On priors, you’re talking about the Cass report, which was in fact massively flawed, and I saw a great deal of discussion on it. Among other issues, they tossed out a lot of studies, and wrote the report from the stance that the only studies worth looking at would have been double blind studies. I’m not sure if you’ve considered this specifically, but it’s pretty damn hard to blind starting to grow boobs or facial hair. Cass, the supposedly neutral party conducting the study, was handing out copies of “Irreversible Damage”, a scaremongering antitrans book about how the poor helpless young “women” were being seduced by big trans. It was garbage, and there’s plenty of writeups on it.
