Yea, well see you have a nice lil label to use. "Skinheads". not all racist white people are skinheads. at the same time their is no label for racist black people. does that mean racist black people don't exist?
The problem is your comparing a small group of white people "skinheads" to a big broad range of black people who live in ghetto's. of course not all black people in the ghetto are racist, but when you use skinheads, you know that white side is ALL racist.
check this out, lets take LA for an example. a black person walks through a white neighborhood, a white person walks through a black neighborhood. who's most likely to get they ass beat?
*EDIT* actually not sure if thats that great of an example because you have to also look at the economic factor. Lets say the white neighborhood is just middle class to low class, not no rich neighborhood...
