the same reason people have cited every time you do this kind of thing. you know the definition of cissexism and transmisogyny so why would you think it is ever ok to group cis men and trans women together by biology for the purpose of insults or exclusion?

it’s such a non-point anyway. body parts have nothing to do with ‘getting an opinion’ about abortion - no-one’s opinion on someone else’s abortion is valid.

i have a womb but i do not have your womb, so neither of us ‘get’ an opinion on each other’s abortion, exactly the same as if i was a ‘semen carrier’

which is why i don’t say to pro-lifers who are capable of getting pregnant, “well you could find yourself in this situation so you get to speak for everyone!”

it’s irrelevant and i don’t see how you couldn’t look at yourself grouping all amab people together with the term ‘semen carriers’ and not think…hmm, something has gone wrong here
