I agree that Obama himself is causing this — just one aspect of his divide and conquer so he can complete his plan for us — What ever it is?
When I first moved to my dominantly black neighborhood in Columbia, MD during 2011, everyone got along extremely well with essentially no racial tensions. But over the past six months, I have observed a strong uptick in harassment by groups of black male teenagers, to the point that I go out of my way to avoid the places where they hang out.
This is the inevitable consequence of the endless race-baiting and blaming white people by the president of the US.
