One of the big causes liberals and race hustlers are pushing these days is what they claim to be disparate school suspension rates for blacks. To accept their theory, you have to first assume that public school administrators, who voted for Obama probably at the 90% rate, are closet racists. Then you have to accept that the only possible reason for the disparity is racism. This mirrors the argument that black men are imprisoned at higher rates solely because fo racism.
Bottom line, the same liberals who endlessly proclaim their support for education, yada yada yada, would prefer to leave violent and disruptive "students" in the classroom if they are black rather than have a safe and productive learning environment for those actually trying to learn. Of course, what do they care? Their kids are in an all white private school with armed guards and strict discipline policies.
