Skinheads are a subculture distinguished by shaved heads. Skins are usually strongly partisan; although sometimes associated with neo-Nazism, their beliefs range from far left to far right. "Sharps" (SkinHeads Against Racial Prejudice) are anti-racist and usually politically to the left. "Trad" or traditional skinheads are apolitical and have their roots in the multiracial working class culture of England's dockworkers.
Unfortunately, neo-Nazis attempted to organize white skinheads leading to the rise of the subculture many people associate with the term. This latter type got their brief day in the limelight when they broke Geraldo Rivera's nose on TV.
