The post which I referred to mentioned "women and men", not "women and transmen".
Transmen are a subset of women, thus specifically mention them is like talking about "humans and children". But mentioning "men" is wholly incorrect.
I agree with transmen and other non-women that they need separate spaces away from women's spaces, as transmen often take testosterone which makes them very different from other women, but they still are adult human females, i.e. women. (And those who can need abortions cannot have made many changes to their bodies, as a testosterone overdose often damages the female reproductive organs)
It is very, very, very silly to talk about "men" (meaning transmen) when it comes to periods, pregnancy and abortions.
The only possible benefit a woman can derive from transing herself is to pass as male and thus gain more safety and financial advantages. Making a big noise about "men" needing abortions, too, makes it harder for women who transed to male to fly under the patriarchal radar, and renders transing completely pointless. (Especially for women with no body dysphoria, who do not want surgery, and who are, long-term, the only group of transmen who can still get pregnant.)
If you don't want to alleviate body dysphoria and happily throw away the opportunity to gain male privilege, why the fuck are you doing it?
