Ok, Boomer.

Nazis are a group of people. Republicans are a group of people. Pedophiles are a group of people.

Admin@beehaw.org currently presents as male and provides his name and other relevant biographical information in his public profile.

You assumed OP’s ignorance of admin’s preferred pronouns. That assumption was unjustified.

You misgendered admin by pressuring the use of gender-neutral pronouns instead of admin’s own, preferred pronouns.

I think you can do better.

Beehaw is pretty notorious for their dictatorial approach to moderation. Pretty useless instance, IMHO.
