Her initial response? "Oh, I don't know. Why don't you go ask them?" *Cackles*:
Her larger response? If gays are allowed to marry and you disagree with it, you'll be called a bigot (according to Gallagher). Allowing my marriage to continue to exist will weaken the institution of marriage because... well, because.
In other words, she skirts the question. "Gay marriage is bad because we said it's bad. And stop calling me a bigot." That's the voice of marriage inequality today, folks!
