Uh, they quite literally were under the law back when segregation existed. Yes there were rich black people and white people who marched with MLK. Zoom out to a population level however and they were clearly distinct groups and treated as such.

Good luck understanding the world while refusing to apply historical perceptions to historical issues.

The historical perception is part of the problem.

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.

Are you saying that in the US during the Civil Rights era, they weren't?
