My friend Lewis Day posted the following on his Facebook page on 26 May 2016. I think it is worthy of reposting. (I have corrected a few typos.)

Someone in a conversation I was following [on Facebook] posited that whites in the US are subject to “reversed racism.” It caused me to think about how to address the claimant.

There is no such thing as revers(ed) racism; there is only racism. Anyone can be racist, certainly, but the effects differ depending on the social and political structures in play.
In America and the west, the dominant cultures in part define the Other via observable racial (for want of a better term) characteristics. It’s true across the West, white racism is a social phenomenon, with the state colluding to greater and lesser degrees. Americans do it, Britons do it, Scandinavians do it, the Swiss, Australians, and Spanish do it. Governments enforce a racist hegemony in alliance with other social institutions, often at the same time as they push measures which combat overt racist acts. The cognitive dissonance is staggering, nowhere more so than in the US.

Racism in America flourishes even as we become a more diverse (in all ways) population, and even as many segments of the population combat it. The struggle is a long one, and chirrupy statements such as ‪#‎alllivesmatter‬ foster continued division by attempting to deny the particularity of American institutionalized racism. The election of Barack Obama did not signal the dawn of a post-racial America, and the reaction of congressional Republicans and their voters provide exquisite proof of this.
