Not into banning things and censorship, personally. All feels a bit bandwagony this. I think it's much better to let idiots expose their idiocy than to ban them.
It's not censorship though is it? We're not stopping them from writing whatever they want, we're just saying "We find your actions unacceptable and no longer wish to be a part of your circus."
Which I, for one, think is perfectly fine.
If you want to talk about infringing people's rights - what about being forced against your will to work with an organisation that you morally disagree with?
