Of course.

However, one can recall that Democrats before the "switch" were kinda racist and kinda liberal at the same time. So it wasn't a complete switch between the parties. And that this is because that kind of "liberal" is, similarly to marxism, about having some "more fair" society, but only the way you want, impeding your opponents trying to change their parts of society the way they want.

That my point is more about fragmentation. Say, from what I've read, it seems that somewhere in 70s you could find towns and districts where you'd be absolutely abused for being Black and there, but you could also find normal ones.

The issue with trying to solve the problem of the former by some centralized pressure is that it creates the same instruments that could be used to "solve" the "problem" of the latter, and worse - introduce new problems.

More than that, structurally it averages to the worse, because crowds are as smart as the dumbest and worst person in them.
