Ta-Nehisi Coates:

Racism tends to attract attention when it's flagrant and filled with invective. But like all bigotry, the most potent component of racism is frame-flipping - positioning the bigot as the actual victim. So the gay do not simply want to marry; they want to convert our children into sin. The Jews do not merely want to be left in peace; they actually are plotting world take-over. And the blacks are not actually victims of American power, but beneficiaries of the war against hard-working whites. This is a respectable, more sensible, bigotry, one that does not seek to name-call, preferring instead change the subject and straw man. Thus segregation wasn't necessary to keep the niggers in line; it was necessary to protect the honor of white women.
