The only thing I think is absolutely clear here is that you don't care for Alan Keyes. I believe you'd find a way to criticize him regardless of his decision. Do you disagree?
No, I don't particularly care for Keyes because he's a phony.
If Keyes had the same reaction to his daughter that Dick Cheney does, I'd be pleasantly surprised and would say so. It would reflect that his Christianity wasn't just an act.
Alas, I was not surprised.
