I for one do not discount this, I think it's more that this doesn't affect men as much as it affects women. So naturally they don't care as much. Not that they don't care at all, just that they don't care as much. They also may just not "get" the real issues.

I was talking to my husband about this yesterday and he asked why women hate being called a "uterus haver". It's because we're constantly reduced to our sexual characteristics. It's demeaning and sexist and just utterly horrible. I asked him whether he would care about being called a "penis haver", to try to get him to empathise, and he just didn't see a problem with it. Who cares? While I deeply loathe being reduced to my sexual organs. Dehumanised, like women frequently are.

That's all. I welcome male allies, like in the now-defunct gendercriticalguys.
