All this proves, and all these parents should have learned, is that they have completely and totally failed in their jobs as parents. And of course, they are likely liberal. Or is saying that a redundancy?
Ah, I see. So, are Dick and Lynn Cheney wonderful parents for raising a heterosexual daughter (Elizabeth) who went on to give them 5 grandchildren, or are they horrible failures for raising Mary who turned out to be a lesbian?
Here's a thought, maybe they didn't have anything to do with Mary turning out to be gay.
