You have no clue what you're talking about.
If we want to talk about real, actual racists, let's tackle the slaveowners who were presidents. Or that vile scumbag Woodrow Wilson. Or Andrew Jackson, perpetrator of genocide. Or any number of men who actually were racists and who didn't have the temerity of offending delicate white folk by pointing out this country has a real problem with race relations.
Calling Obama a "racist" is so clueless, so utterly out of touch with reality, that it comes close to self-parody.
...and to ignore his obvious racist behavior is to continue in La-La Land! He has poured out unctuous sympathy to black victims and their families whilst virtually ignoring victims of other hues.
