"Umm... Where are the black people?"
Reminds me of the time I was smitten with a bookish, highly intelligent and fun woman who was rather to the left, politically ... she insisted that I go to a speaking engagement by an author she loved, who proceeded to go on and on at length about how important it was to break down racial barriers and to go out and educate the world about the evils of segregation. The entirely white, liberal audience nodded sagely and practically patted themselves on the back for their enlightenment, and didn't understand at all why I found them amusing.
