So we should just cater to the irrational whims of ignorant parents?
Gay /= pedophile. It really doesn't get much simpler than that. The fact is, most guys who molest boys identify as straight. As the feminists will tell you, rape isn't about sexual attraction. Same thing applies in prison. Those guys aren't raping each other because they're horny. It's all about dominance. The motivation in child sexual abuse is different, but still independent of gender preference. The simple truth is that a straight man is more likely to bugger little Billy than a gay man.
Also, if you want to go to absurd lengths to prevent this sort of thing, I'd say that the Catholic Church is a much more dangerous element than homosexual scout leaders. The Roman Catholic Church ranks third on the list of charter organizations. I'm sure they'd like you to believe that all of that molestation was a gay thing, as well. Part of the reason the Catholics are having the problem that they are is because of the very mentality that the BSA continues to promote: molestation is a component of the homosexual lifestyle. You can always count on the Church to be the last ones to emerge from the dark ages, but on this issue they have a lot of company. By continuing their archaic notions that molestation occurs in their respective organizations because of infiltration by gays, they will continue to foster an environment where the real dangers go overlooked.
Lastly, I really didn't want to reply to Orbert's sarcasm, but there's something there that really needs to be addressed.
...I'm sure that all the parents of adolescent boys would have no problem with their sons being off on a weekend camping trip under the careful supervision of gay men. It would never occur to them that anything unsavory would occur. None would ever question why gay men would choose to devote their weekends to spending time with adolescent boys.
Frankly, I'd be curious why any adult male would choose to spend there weekends with adolescent boys. I suspect the rationale is the same regardless of their respective sexualities. I'd certainly expect any parent to exercise some diligence in checking into the background of people who choose this lifestyle. To just assume that the BSA has it under control because they exclude gays is just asking for trouble.
And just to reiterate, I still defend their right to exclude whoever the hell they want excluded, so long as they keep their organization away from public money. Personally, I'd find their stance much more reasonable if they'd just come out and say "we find homosexuals to be creepy as fuck and we don't want to associate with them," rather than the bullshit fear-mongering they throw around as justification.
