I'm personally on the side of not giving this type of content a platform to exist in, but the challenge with Bluesky seems to be that they're effectively centralized as a platform despite technically having the ability not to be... meaning the burden of moderation falls on a tiny team to please well over 20 million people. I reckon the pressure is becoming a problem.
I know for sure these hateful zealots would immediately be banned and booted from my instance, that's for sure.
