I don't know much about them. Apparently they cause a bit of property damage. Troublesome, but at least they haven't driven a car into a crowd of people.
@TotalMiss What does that have to do with it being on Wikipedia? Besides, Nazism is a political movement, not an ethnicity or nationality, though it does have stances on those things. Hitler was Austrian after all, and one of the most common American ancestries is German anyway.
@TotalMiss Actually Nazi is a purely English term. In Germany the party is NSDAP. That's all beside the point though. The ideology still exists, and has people who identify with it.
