Thanks for the links. I am well-versed on hate groups and the masks they hide behind. It's something I was responsible for tracking, at one point, for a specific community of people.
In fact, it's what finally got the city police of my parents' town, to evict squatters on their street. One of the cars had a window sticker that seemed like it was for a skateboard company, or a band, or whatever. When I looked at it I immediately recognized it, told my parents, they told the police (who had an open file on this house and the occupants) and two days later the house was empty. Apparently the police visited and let them know what's up, and the squatters vacated that night.
Fun and games. :(
