Heavily pregnant transmen in maternity wards aren't likely to be mistaken for men, whichever way you cut it, so that argument falls flat straight away. I don't care if women dress 'as' men - I don't see clothing as necessary gendered, tbh. Women's fashion is far more flexible than men's, so a man in a dress stands out far more than a woman in trousers, but for the millionth time, it is not I (or any other gender-critical feminists I know) who thinks that clothing or 'presenting as' a gender is linked to sex. Quite the opposite.
It's not 'funny' that arguments are not addressed. It's far more likely that they simply haven't come up or been considered. I doubt that many of us spend hours thinking about any of this - I just respond on here when I see blatantly anti-feminist things posted in the name of 'inclusion'.
The sentence about 'the extent of my feminism' makes no sense to me however I read it, I'm afraid. The one before it is not true, although as I'm not a follower of sport I fully accept that there will be lots of things that pass me by. As I've said, I'm not obsessed with trans issues, and that, plus my lack of interest in sport makes it very likely that there are things I don't know. The argument that not wanting men to compete against women is somehow akin to racism (or was it Nazism?) is laughable, though, as well as being offensive.
