Skinheads were a punk-adjacent subculture that got overrun with neonazis. They never did shake the association.
The neonazi invasion happened around when both tended to show up in the same discussions. More people know about punks than skinheads, so I used one to give context to the other. The recent movie about the late '90s punk scene, Bomb City, even had a skinhead with an anti-Nazi jacket.
