Yeah this is a fear mongering tactic, and an intentional overreach.

The Nazi bar problem is not even hard in concept. If someone is not a Nazi, let them in. If someone is edgy, let them in. If someone is a Nazi, kick them out. Not rocket science. Nazis will not accumulate if done this way.

But people get looser and looser about their definition of Nazis, which ends up being “people I don’t like or who have different politics agendas than me” and pre emptively kick out tons of people in the name of keeping themselves safe
