Zombie says that the "privilege" line is actually a class issue, not race. But not really, not for progressives. Race is class. Just look at those signs. Indeed, racism is all progressives have. Well, they had the antiwar movement too, but --- except for perhaps the most hardened communists --- they hypocritically abandoned it when the first black president took office. Amazing consistency. ASFLs.
