Well, when my kid was younger I would have been uncomfortable about it to be honest. That was several years ago though and my understanding of these matters has changed a bit; people on DP have shown me pretty convincing studies that "gay" and "pedophile" are two different things that aren't really linked. Five-six years ago I had my doubts about that, but you live and you learn.
Now, my boy is 17. We've thoroughly established that he's straight and likes the young ladies, and I gotta admit that's a big relief to me. However he goes to high school with gay and lesbian teenagers; his "lunch hangout group" includes a lesbian girl.
It's just the modern world, the way things are now, and at some point you just have to deal with it and carry on.
When I started public school over four decades ago, racial integration was a new thing, and a lot of people were uncomfortable about it; the parents more than the kids really. It was the new reality though and eventually everyone had to deal with it and carry on, and eventually it became no big deal.
Things change, and that's all there is to it. You deal with it and carry on.
With that said, I figure it is the BSA's chicken, let them pluck it their own way.
