The theory of structural racism runs into serious difficulties when confronted with the data.
Holding genetic ancestry constant, Americans who identify as Black or Hispanic achieve educational and income outcomes that are comparable to, and in some cases better than, those of Americans who identify as White.
In other words, the observed disparities appear to track genetic ancestry more closely than socially defined racial categories.
This is the opposite of what structural racism theory would predict: if social outcomes were primarily driven by discrimination against socially constructed racial groups, racial identification should remain predictive even after controlling for genetic ancestry.
It's so easy to debunk these folks. A $49 annual subscription to newspapers .com is all it takes. It seems these fine Negroes were stealing, rioting, and plotting to kill the good White folks of Arkansas. Imagine that.
