If someone with the username "Proud Anarkiddy" tweeted about how anarchism is all about some cringey nonsense, would you post a screenshot of that? Hell, it doesn't even have to be political: if "StarWarzNerd69" tweeted about Star Trek fans being basement-dwelling virgins, I'd ignore the obvious troll bait.
I might find your argument convincing if it weren't for the fact that every single person I've interacted with on your instance was less reasonable than anyone off of it.
Hexbear is absolute trash that has permanently driven a lot of reasonable people away from the fediverse while spreading malicious authoritarian propaganda.
