It's not like camp is a hook-up environment. They don't require any sort of "catering."
There is only one difference between gay people and straight people: who they prefer in romantic and/or sexual relationships. Camps do not cater to romantic or sexual desires. So what is the issue?
If there is an emphasis on story sharing at the camp, I think gay attendants should feel free to share their stories about relationships or coming out. But that isn't "catering" any more than it would be to say that someone can share their religious and family experiences, since each is unique.
How about we treat people as individuals and only condemn them when they actually do something worth condemning.
