I guess everyone has a different idea of acceptable language.
Datun's posts are very direct.
As are terfinator's.
The nastiness isnt' saying "Paris: to me, you are a man and therefore xyz".
That's the same as a man saying to me "Thanksfor, in my opinion, because you are the wife, and so you should be the primary carer."
In both cases it might be considered oppressive but it opens up a right to reply.
It's the snarking snippy "oh it is a transmaiden" type stuff that would break me. So if transwoman X is asserting a right to be called a woman, it's fine in my book to answer straight back saying "I consider you to be a man" but not to add in a snarky "oh look what he's saying now!" in a sort of "did you see what I did there?" kind of way.
However, as has been pointed out before, I am not the language police.
