That's the standard gay talking point, but the truth is that only gays are a sexual threat to boys. It's like letting an adult heterosexual men lead a group of girl scouts.
Are you saying that adult heterosexual men should not be involved in girl scouts? How about coaching girls sports teams? How about adult heterosexual men teaching adolescent girls in school? Are THEY all sexual threats to girls?
Come on. Adults of the opposite sex have been teaching and mentoring kids of all ages since time immemorial, and the vast majority of them have not been sexually predacious on those kids.
Like I said before, if you want to ban gay scout leaders because it's a moral affront to the BSA, that's justifiable. But if you want to ban them to "protect the children" you're talking through your hat.
