So are posters who want to grandstand about something other than the comment they're responding to.

Original comment cited a historical example relevant to the posted article. You responded that the comment implied (in the present) that whites and blacks are two different groups, which they never did except in a historical context. Therefore you either disagree that historically whites and blacks were two separate groups in post-war America (good luck arguing that) or you're trying to contort the conversation to a discussion of "the problem" whatever that is in your mind.

The latter, and i think it necessary. I'll gladly hijack more threads to point it out until enough people are aware of this annoyingly subversive detail.
