No, of course not - but unless I missed something, I don't think anyone said she should.
I think it's possible that she isn't the only one who looks a little bit bad here, though, if the breaking point with Maya's behavior came only when she went public - but, like I said before, it's his family and he can handle it the way he wants to.
My problem is that he went ahead and allowed the issue of homosexuality to be personalized in a negative way with the Cheneys' daughter, all the while knowing his own daughter was a lesbian.
I think that was a mistake on his part.
Like I said, his heart is broken, put yourself in his place.
