Real skinheads are not racist!! It originated with the reggae (of the Jamaican immigrants) fusion with mod (working class kids) in 60s uk. Many early skins were Jamaican, and many skins world wide are of every race and culture under the sun.
The skinhead culture in the UK derived from working class young people. The CCCS of the Birmingham Universities studied youth cultures and named them sub-cultures because they were resistant to mainstream culture. The skinhead culture resisted beauty ideals by shaving their heads and their clothing style (boots, shirts and braces) represented that they are working class. Skinheads emerged during a time of the erosion of the working class. Their particular style had symbolic resistance.
