I believe the kids were mostly talking about whether other boys who thought they were gay would be allowed, not scoutmasters.
I don't know if the article is intentionally trying to mislead or what, but as far as I know, the Boy Scouts does not ask or ban boys who claim to be homosexual from being a Boy Scout. The Boy Scouts ban on homosexuality has to do with it's leadership. That being said, aside from our yearly abuse/safety talk with the boys, the topic of homosexuality isn't discussed.
I am a leader (committee member) of my boys Scout troop, and that is how I understand it. One thing that gets constantly reviewed for us leaders is the two depth leadership rule. It is not just for the boys safety, but for ours as well. If a leader puts him or herself in a situation that even looks compromising, it can lead to trouble.
One other side note: if there are only two adult leaders and one of the leaders has to escort a Scout somewhere, we are required to bring along another Scout. This minimizes the problems of a “he said-he said” problem.
