Some state intervention (e.g. drug prohibition) creates issues (in this case mass violations of civil liberties, militarization of police, vast numbers of incarcerated minorities, criminalization of medical conditions) that are measurably worse than the original problem it intended to solve. I don't know whether that's the case here, but it's worth asking. You'd better be certain that hate speech online is a serious enough problem that it is worth the cost, and you'd better have a good idea of what the cost will be.
