You know - I haven't thought a lot about it. On one hand I think it's fine to have private groups that exclude. There are plenty of them.
On the other hand, the gay issue is not much of an issue to me. Gay boys everywhere will get to learn how to camp and build fires I guess.
If you are asking because I'm a Christian, the "command" I need to live by is to love God and love people. "God" is specific, and "people" is broad.
Maybe a gay boy will become a Christian. Maybe a Christian will become gay - either of these scenarios could also become a reality in a classroom, playground, baseball diamond or ASB.
