I wouldn't be surprised. We're doing a very poor job of educating our kids on the matter. The younger generation supports it, thanks in part to our schools, our media, and our unwillingness to speak to our kids about the matter.
This is just pop psychology and anecdotal evidence from me but I have known and still know quite a few homosexual individuals. I can honestly say that their lives look to be very difficult and sad to me. There is a lot of pain there and I think that our young people in junior high and high school don't realize this.
