I agree, it seemed to begin with the skinhead 'revival' in the late 70's. The 'skin's' of the late 70's really pissed me off, as they had no real connection with the original skins of the late 60's.
Skins in the late 60's/early 70's weren't racist, listened to reggae, ska & Motown, and dressed stylishly - Ben Sherman, Brutus, Sta-Prest, Squires Brogues, we were the f*ckin' business! A lot of skinhead gangs were multi-racial, and wouid fight anyone who fancied their chances, using just fists and boots, great days.
Generally speaking, the 'skins' of the late 70's were racist, and had no fashion sense at all. I've no idea where the Nazi sh*te came from, but I can say categorically that by no means all Chelsea fans agreed with it or participated in it.
