Politically correct racism

As usual, Ta-Nehisi Coates nails it. I won't be too hard on Michael Moore, because I am sure I have been guilty of saying something similar, and plenty of good liberals I know occasionally lapse into ethnic generalizations; these are "permissible" if they point to what are considered positive rather than negative cultural attributes, never mind the casual empiricism and questionable sociology. Let's all agree to stop doing it.
