Do Preferentialists Prefer Plessy?
I think so. I think anyone who defends racial preferences must reject Justice John Marshall Harlan's stirring comment in Plessy that "our Constitution is colorblind" and agree with the majority's holding in that case the 14th Amendment does not require colorblindness.
In that regard, it is no accident (as we deep conspiracy theorists always say) that today colleges are vehmently defending some programs that altogether exclude students on the basis of race. See my discussion of their behavior several posts below, here, and especially the comments that have recently been added.
