I honestly don't see what's wrong with her response. He asked a truthful question, he got a truthful answer. I don't like your title of the thread either kballa. Just because she said she think marriage should be between opposite sexes doesn't mean she hates gays.
I personally thought the answer was somewhat polite and the answer was somewhat diplomatically right or however they phrased it. She stated her opinion, which is what the question is supposed to do. Everyone is just flipping out because she was SUPPOSED to say yes. But they didn't hear what they wanted so they flip out. She's perfectly fine in my eyes.
