Regrettably it isn’t that clear cut. While hate is illegal—and rightfully so—racists, bigots and war mongers can and do find ways to spread their hate with legal means. This includes shorthands, dog whistles, framing and tones, etc.[1] I don’t think we will ever be able to conceive a legal framework that can catch all these as hate speech. So we need moderation along side criminalization of hate speech.

Then why would Facebook be able to conceive a moderation framework that can catch all these? The underlying problem to be solved is the same, it has just been removed from democratic scrutiny.
