I appreciate that you find it scary but that is to a large extent what it's like where the rubber meets the road. Pejorative political labels do get tossed around too easily, but there are are also honest-to-goodness violent neo-nazis and other fascists that go far beyond shitposting into planning and carrying out violent acts. Sadly, some of those people infiltrate law enforcement or the military. They're not hiding around every corner, but there are quite a lot of them and they are not all like the clowns that get themselves arrested in really obvious ways.
