The decision by many in the media to capitalize Black and lowercase white is pure racism - implying that Blacks deserve an honorific of sorts and whites must be assigned to a lowly and inferior position.
Some deny the subtle message being spread with this double standard, so I suggest that for today only we refer to Whites with a capital and blacks in lower case. That should make it apparent how racist this practice is.
After that, I suggest we follow The Atlantic’s suggestion: that we treat both races the same, and either capitalize both or lowercase both.

The Case for Capitalizing the 'B' in Black
Black and white are both historically created racial identities—and whatever rule applies to one should apply to the other.
