“If mothers ruled the world, there wouldn’t be any [expletive deleted] wars in the first place.”

You’d think that she would know better since she’s been in TV most of her life. I could add something snotty about how arrogant and empty headed it is given the fact that we’ve lost more lives through abortion than through all the wars combined.
Update: I’ve decided that was too harsh. It would have been enough to refute her claim with Margaret Thatcher and the Falklands War.
