I watched those videos and a couple of others listed on the right hand column that were similar to somewhat similar in content, and then the infamous 1988 skinhead brawl on the Geraldo show popped up. Rivera's nose was broken by a thrown chair during the melee. That was back in the heyday of Tom Metzger and the skinhead movement in the U.S. Metzger's son John is on the show along with a couple of other young White guys, though none had shaved heads. I don't think any of them are involved in White racialism anymore.
Most skinheads were too identifiable and thus were easy targets to get in the prison system; I don't think there's more than a very tiny skinhead scene these days. Ironically, shaved heads have since become mainstream.
