"Each tends to reinforce the other." Yes. This. It is important to consider the time component because of the difference in inertia. Institutional racism can be legislated against immediately(Harry Truman and the military) with enough push, but cultural changes require generations. Not knowing and addressing the differences encourages blowback and moneyed interests feed on that chaos. I'm not implying that legislators should hesitate, but that community forces have to be encouraged to embrace change, rather than allowing marketed propaganda just fight it out.
