As a trans person, I feel the need to say this for the cis so that y'all don't need to tiptoe around it or keep quiet:
Trans people are not immune to being awful people. You may not know if someone is really trans or not. But you can tell with much greater certainty whether or not they're an asshole. So stick to that instead of getting baited into bigoted language.
Asshole is gender neutral. 👏
