I was in the cub scouts/BSA from elementary all the way up from Eagle. Its a little bit like the military during don't ask don't tell. There were gay people inside the organization and as long as they didn't try to grab your cock and balls in the shower nobody really cared. It is a private organization though and I don't think it should be forced to do anything. I mean where does that end?
If people don't like it isn't a mandatory thing that you have to attend.
I'm pretty sure though that it will evolve in its own time to where in a couple of years it will see how backwards the philosophy is, especially when it already has plenty of gay members within its ranks.
