The response that most encouraged me was the woman who said she was raised Catholic, and she thinks evolution should be taught because the Catholic church has no problem with it, and accepts evolution (although they do of course go for theistic evolution, but still). Why do I find what she said encouraging? Because out of everyone there, she was the only one who didn't necessarily throw science out the window just because of her belief system. The majority of Catholics I know have no problem with evolution. Anyone living in the Bible belt, hearing that response, might just have thought "hmmm... you mean, someone CAN be OK with evolution?" and maybe it got someone thinking.
I'd sooner see someone accept theistic evolution than outright creationism. At least that way, you've got some ground you can talk with them on.
As for any of the beauty pageants themselves... I refuse to watch them. Like BCE and Tank said... like a cattle auction.
Also, for the other responses, I think some of them were carefully calculated to be as non-committal as possible. Saying the wrong thing can get you eliminated long before the swimsuit round.
