I don't know which communities you're talking about, but anecdotally I have to say I've found trans bars and support groups to have a much broader range in race, class, and origin than any other places I typically go.
Also, low testosterone you describe in that paragraph is not implicated as a cause of transgender behavior, with people generally being in the typical range for their birth sex before transition, which includes outliers with very high testosterone levels. Giving people additional testosterone has been tried and not been found to "cure" transgender behavior.
Relying on made-up facts for an entire paragraph of your purpose statement is not very encouraging.
According to wikipedia:
The androgen receptor (AR), also known as NR3C4, is activated by the binding of testosterone or dihydrotestosterone, where it plays a critical role in the forming of primary and secondary male sex characteristics. Hare et al. found that male-to-female transsexuals were found to have longer repetitions of the gene, which reduced its effectiveness at binding testosterone.[18]
So maybe the amount of testosterone would be normal but it would have less effect?
Through LessWrong, I've discovered the no-reactionary movement. Servery says that there are some of you here.
I'm curious, what lead you to accept the basic premises of the movement? What is the story of your personal "conversion"? Was there some particular insight or information that was important in convincing you? Was it something that just "clicked" for you or that you had always felt in a vague way? Were any of you "raised in it"?
Feel free to forward my questions to others or direct me towards a better forum for asking this.
I hope that this is in no way demeaning or insulting. I'm genuinely curious and my questioning is value free. If you point me towards compelling evidence of the neo-reactionary premise, I'll update on it.
