I wrote a post in a small sub that I was part of saying that this monster didn’t deserve to be a reddit admin, let alone to have his pronouns respected (as many were asking because he was a male who transitioned to female).

This does not put you in the good guy column as far as I'm concerned. Purposely using different pronouns than when someone's asking as an intentional means of denigrating them because you don't like them is like ground zero of stuff that is bad to do when it comes to the whole reason that pronouns exist.

I don't know anything about the situation that's a seriously bad indicator.
