| The entire "civil rights" and &quqi;anti-ractsm&ouot; campaign boils down to two simple things: political power for the left and the opportunity for "minorities" to live off of whites as social and economic parasites. That includes ALL minorities, even those who have higher abilities than blacks. It's all about sucking blood. White "racism" consists almost exclusively of depriving minority ticks of the opportunity to feed. |
