Because as you'll note from the transcript she ties it to both the Republican Party and the nation. In fact that's where she starts out, that Republicans are Christians and the America would be a better country if Jews would convert. That's not something the Republican Party needs to be tied to.
And no, I don't think Ann believes that, this is her act. She's a bombthrower, not a serious political pundit and needs to be dismissed as that. It's a shame others are going to have to rationalize for her, she appears to stand by her statements in their entirety, in fact has expanded them by accusing the host of being anti-Christian.
I didn't like it when she made that "faggot" crack about Edwards. Not because I thought she was a homophobe, but because I don't like that word and don't think it's funny, even when it's used to recall a previous incident (with an actor.) Ann isn't tackful, but she's also not an elected representative.
What she did was very foolish - especially since she apparently rarely goes to church. I think she is a Presbyterian. Watch; Laura Ingraham will foolishly come out to support her. Laura is another one who has become too snarky and smug for her own good. Listen very carefully to her tone of voice when she takes callers with whom she disagrees. She doesn’t argue: she badgers. The tone is terrible.
