Yep. The best thing to marginalize the KKK was the Skokie march in 1974. Sunshine is the best disinfectant for extremism. A White Supremacist march today is lucky to get 100 people. Let them have their say, it inevitably leads to disdain, scorn and impotence. This is a lesson the Social Justice Warriors will not learn until they are the Left’s form of the KKK.
In the mid 70s, a KKK rally was announced in advance for a Saturday in the small town I lived in (North Carolina). Turns out there were 5 or 6 klansmen gathered at the town's main intersection. Everyone passing by (black and white) laughed at them. They never showed their faces again.
