I'm no more well informed than most posters on here but I do look things up, think about and read them which is what most of us do. What prompted me was you saying that someone posted transphobic stuff; that surprised me. I could not, still cannot, see how any of it is transphobic. People are entitled to question and to seek to understand. One could say you are biased or have a vested interest, I don't know and neither do I want to know.
Since my last post I have been reading more about autogynephilia, in particular a writer called Miranda Yardley (I won't post any links because of the failure of the last two but there's plenty of stuff with her name on it), and she did say that some children present with autogynephilia. So I have learned something.
Nowhere did I read that 'autogynephilia' is a perjorative term. 'Transbian' may be as it is more colloquial but that depends on context.
However I am now going to eat and try to think of other things for a while. Hopefully others will have something to say.
