I've been reading your comments with a lot of interest, but I feel like you took the easy road out on this reply. I think it's clear the OP isn't talking about single instances where someone verbally abuses another person. I agree it's useful/fine to criticize political leaders or for a rapper to diss another rapper. What we're actually dealing with in practice are people instigating hate for other groups of people, in some cases often the same fascist rhetoric used to incite violence (and the acceptance thereof) in Nazi Germany (yes, Godwin's law, yada yada), where do you draw the line?

Do we philosophically want to live in a world where people can be incited to great amounts of violence just because we want to protect FoS on private platforms?
