Compare how Republicans treat Obama with how liberals treat Clarence Thomas.
A white liberal member of the House called Justice Thomas "Uncle Thomas" for not agreeing with the liberals view of how the court should rule. Can you imagine what the reaction would be if a white Republican called Obama an "Uncle Tom"? But because Justice Thomas is not a liberal he's fair game for racist liberals.
To those racists Blacks are only ok if they know there place; supporting rich white liberals.
If liberals weren't racist they'd be fixing the inner city schools that deny most Blacks a chance at success. Instead liberals ignore the plight of Blacks; that's because liberals know that as long as blacks think their very life depends on liberals they will vote liberal.
If liberals weren't racist they'd be worried about the insanely high murder rates for Blacks in our inner cities. Instead liberals only care if a white person kills a black; that's because they can use that to advance white liberal causes.
Obama is a big fan of Planned Parenthood even though the leading cause of death for Blacks in America is abortion. And liberals love him.
