It depends on the kids. I know some really sweet teens who have come out as gay. One of them was in our church group, and my kids did tons of things with him. My son probably shared a tent with him at some point.
I agree that MOST gay kids are just fine...however, if your son shared a tent with a gay male, it would be the SAME situation if you let your daughter share the tent with a straight male....neither a good situation....they are kids and sometimes they do stupid things, like cuddle up "JUST TO KEEP WARM"......
