> Because bigotry against whites is a sideshow, a minor issue.

Then why all the resistance to addressing it? If it's such a small problem, it should be a simple and harmless thing to tackle it along with all the other kinds of bigotry. Carefully policing what kinds of bigotry are to be addressed or not sends the implicit message that some kinds of bigotry are OK. It also makes the overall anti-bigotry project harder because it turns what could be a universal moral appeal into a targeted condemnation that elicits defensiveness and justified accusations of hypocrisy.
