There have always been closeted homosexuals in the scouts, and if anti-gay splinter scout groups form, they will also have closeted homosexuals. Only fools would think otherwise. I met many closeted homosexuals when I worked at a boy scout camp and it was not a big deal. I'm still trying to figure out if Scouts actually attracts homosexuals because of all the male bonding, or if the number of homosexuals there is in proportion with the general population. (I wonder the same about ministry/priesthood--are there any studies about that??)
As an eagle scout-turned-athiest I have a lot of conflict about whether to get into scouting with my 1- and 2-year-olds when they get old enough. I wish they could keep all the fun stuff but abandon the high-minded judgmental morality. Whether a 12-year-old has belief in God or not and whether they like boys or girls has no bearing on their ability to have fun and develop camaraderie and character through civic activities. It makes me pretty angry that there are so many stupid judgmental ignorant asshole parents out there who must foist their morality on innocent kids who just want to go camping and canoeing. But scouting has been in decline for decades so this issue is not going to "kill" scouting as many say. It's been on its way out for a while. I actually think that as the zeitgeist changes regarding homosexuality, the scouts willingness to become more tolerant can only help it survive, if only for a while.
And a final comment: the scouts' new policy is that homosexual scouts are allowed but not homosexual leaders. While that policy may ostensibly be about having morally upright leaders (offensive in itself), the thinly disguised subtext is that homosexuals are likely to be pedophiles. I've followed this issue and I wish more people would call them out on that wildly offensive implication.
