I think about the Nazis and Skokie all the time. "You have to let the Nazis march in Skokie" is a sort of a mantra for my friend and I, especially when what we would like to see happen to the individuals or institutions in question cannot even be expressed with decency. However I failed very badly in this principle when they banned Trump from Twitter, so it is not just the young, it is eternal vigilance for all of us. I've often thought there should be a high school course on how to evade used car salesmen, advertising and politicians. This would be a great beginning!
