No, and it's quite possible the info I had read was anecdotal. I have spent more time than I should in the literature on transgenderism in an effort to better understand my kid. The problem I quickly found is that solid info is hard to find, as most is propaganda for one side or the other. I also found that sources outside the US often tended to be less political and more data driven. But admittedly the "Terf" movement in Britain may be the source for my original thought, and that would certainly make it anecdotal as they do not represent mainstream LBG views in the US.
