The talk of race clouds the meaning of what’s really taking place. Obama’s strategy is as old as history and doubtless occured in ancient Babylonia. Being energized by a spirit of pride, lies, hate and envy he lusts after power to dominate and punish those he hates, hence he sows seeds of discord among those he thinks are most like him therefore most likely to respond in kind, to go forth and destroy, terrorize, coerce and plunder.
It's called being a demagogue. Appealing to the emotions of the crowd rather than to reason. Obama is certainly a master at demagoguing.
