It is quite a stretch to refer to using the word "woman" to describe someone who is pregnant as treating trans males like shit.
And yes actually, trans males would feel like they are being treated like shit by the people in this thread absolutely insisting that gender == sex.
I support trans rights; what I dont support is the intellectual terrorism that underlies the notion that just because someone has a legitimate difference of opinion on appropriate language use, they are "treat[ing] people like shit" or worse.
