As someone who is outside all this, but has a reason for knowing a bity about it, it often seems to me that there is misunderstanding about this business of whether a transsexual woman " is a woman". It is a matter of courtesy, not denial of biology. The law makes it clear when the GRC is issued; this person is " for all practical purposes", now of the new gender.It does not mean that the chromosomes have changed. ( Incidently the XX and XY thing that is constantly trotted out is misleading. Certain ambiguous and intersex conditions are much more common than our society assumes..... so if you know a lot of women, you certainly know one or two who are genetically male. Though they are unlikely to know it. ) . I can't see why some of us constantly shout that "someone born a man IS a man, and you ain't fooling us" . It seems not only unkind to transsexual people, who have enough abuse to deal with anyway, but also it kind of misses the point. If someone has been aware that they are transsexual all their conscious life, has gone through social barriers, often losing family and friends, and messed up a career in some cases, has swallowed hormones, undergone lazer or electrolysis, had invasive surgery , and has mucked about with their natural speaking voice to try to look and sound reasonable; well, why can't we show them a little common decency?
It is true that some m to f trans people talk rubbish about " being 100% woman now ", and don't like to talk about prostate, or narrow hips, etc., but they are usually young, and gender dysphoria seems to send people loopy. Only cured by transition/ hormones/ surgery.
There isn't very many of them, anyway. There is no chance that they can "take over " even if they wanted to, and most I have met by now don't want to do any more than live their lives in peace. There is quite enough trouble in their lives without extra harassment from trans exclusionary radical feminists.
