If you want a big tent, you need to push out the assholes. Otherwise, the only people who remain in your tent are the assholes and people not attacked by the assholes.
See how this naturally gives a lot of power to the assholes? When you allow assholes, they decide who remains in your tent, by pushing out those they don't like.
You cannot be politically neutral by allowing everyone. That just creates an environment where a very specific ideology thrives.
If you truly want an organization where people of any political leaning can join, then you need to exclude the very small subset of people that hate, ridicule, and maltreat others.
Some of these people will claim that their hate is part of their political leaning. And that's fine. We don't care why you're an asshole. We just don't allow assholes. Period.
I disagree with "Hateful and hurtful actions are an inherent part of some political or religious beliefs."
It doesn't matter for our community whether you agree, because assholes should be avoided regardless of why they're assholes.
But I do want to puncture this myth a bit. I've met very nice people from many very different political and religious backgrounds. The vast majority of people I meet are not assholes and know to shut up when their thoughts would hurt others when said aloud.
I'm not going to say to a new mother that her baby is ugly. Who does that? But for some reason when people are assholes to trans people, then it's suddenly acceptable to be an asshole?
Some hurtful words and actions are accidental and caused by misunderstandings or a lack of context. And that's fine! There's a super easy way to distinguish between accidentally hurtful actions and intentionally hurtful actions: how do people react when they're called out.
Decent people know when to apologize.
