From a comment by Brock at Belmont Club:
I’ve been saying this for some time. The American people are (largely) not suicidal, and will demand to know who is responsible, and they will therefore seek out the variable with the highest degree of correlation. But if some of the variables are hidden by law, they’ll use the (less precise) visible ones: race, ethnicity, gender, religion, national isotretinoinofficial origin. Every Leftist and Imam professes to be afraid that Ethnic Profiling or Religious Profiling is coming, but if they continue to prevent the rest of American from engaging in Ideological Profiling, then Ethnic Profiling is what we’re going to get. Lots of innocents will be harmed, but Americans will feel safer and think “It’s the best we could do in a bad situation.”
