That's a good question.

As for Oprah--I like her very much, admire her, and feel great affection for her; she is obviously brilliant and a profoundly good person. However, she will fall all over some illiterate rock star or some brainless "celebrity" but show no evidence of admiration for someone as brilliant, outstanding, and worthy of admiration and respect as Condoleeza Rice and President Bush.
Research studies now project that one in five - listen to me, hard to believe - one in five heterosexuals could be dead from AIDS at the end of the next three years. That's by 1990. One in five. It is no longer just a gay disease. Believe me. OW in 1987
Does a brilliant person fall so readily for such obvious propaganda?
