I don't think horrible people (eg racist, xenophobic, bigots) have the right to share space with good, kind people.

They have the privilege they forfeit the moment they try to hurt others. If they don't behave like cunts I don't care, but if they do, I'll use any tool I have at my disposal to bar them from the space they don't respect. They can talk to their kind in the nasty spaces anyway, so it's not like they're in the solitary confinement.
