A firmer stand needs to be taken against all accounts used to promote hate and violence, and not just those from the alt-right on which the story seems to be focused.  Right wing groups like white nationalists and the KKK are despicable lots, but so are left wing groups like Antifa and Black Lives Matter, the latter which has openly paraded thought cities with hundreds of supporters shouting “What do we want? Dead cops.  When do we want them? Now.”   They all use social media to spread their sick messages of hate and to organize protests and rallies.  They should be shut down. The question is How?
