The problem is not just the white nationalists and Neo-nazis, but antifa as well. Neither side wishes for the other to speak, and if they do, it is labeled "hate speech". The best remedy to hate speech is more speech to counter the deluded message. When antifa tries to silence Coulter, Shapiro, Milo & Murray, this causes middle of the road Americans to bristle.

The best disinfectant to bad ideas is good ideas. This is accomplished with free speech. Let both these groups, Left & Right, be marginalized by what they have to say rather than pick up steam by being misdefined by their enemy.
