Earlier quoted context omitted.
Doxxing is not free speech. The sensible majority of people understand that. It's only a vocal small minority of idiots and troublemakers that argue otherwise.
My preferred operationalization of free speech is "minimum intimidation". Slurs don't qualify for protection under this operationalization, because they intimidate the listener without providing any information content. Same goes for protesting a talk so loudly that the speaker is drowned out, or doxxing. If your speech serves only to intimidate others into silence, I don't think it should be protected. Curious to he…
Anyway to me it's similar to saying "violence is bad," yet we probably both believe people should be allowed to emoloy violence when violence is being done to them.
I think similarly applies to hate speech. If a nazi shows up to campus to deliver their message of hate, it's ethical to drown them out and prevent any spread of the hateful message.
"But both sides but hypocrisy but free speech"
Imo tolerance is not a universal ethical position but instead a peace treaty. Peace treaties should not be suicidal. If you make a peace treaty with someone and they attack, you should abandon the treaty.
Hateful speech (slurs etc) are a form of attack, they're a form of violence. They don't have a place in civil society, civil society should not allow this sort of speech or behavior in it. Someone who is saying these sorts of things is telling you clear as day that they don't tolerate some part of you. So why should you tolerate them? They've abandoned the treaty.
What that doesn't mean is that civil society should go out of their way to hunt and kill anybody that likes to say slurs: that's the opposite of a peace treaty. More like they should be rejected utterly from participating until they're willing to again subscribe to a peace treaty (by being civil, not attacking people).
Deplatforming vocal racists is thus ethical. Their language is attack on civility and our ability to maintain peaceful society.
It's an important distinction.
