Tolerance of intolerance breeds intolerance. It’s the ‘Nazi Bar’ scenario.
You run a bar. One day, a blatantly obvious Nazi comes in, be he keeps to himself and doesn’t bother anyone. A week later, he comes back but he has some Nazi friends with him. You notice some of your regular patrons get up and leave. Over time, the number of Nazis that show up to your bar increases while the number of regular customers dwindles to nothing. Without intending it, you now have a Nazi bar. If you’d have just kicked the first Nazi out, it wouldn’t have happened.
Can we just… leave him there?
