Over here it's hard to tell if they are being oppressed for being in the lower class or being oppressed for being of the wrong race. Both happen on a regular basis, and it's often some mix of the two combined.
Idiot right wingers use that uncertainty to deny that either racism or classism is a problem. Idiot left wingers claim their particular group is the primary target of all opression because of one particular trait and deny that any of the rest of it is a real problem.
