The problem with your statement as it pertains to this case was that there was no evidence that Sanusky ever lived an openly homosexual or faggot lifestyle outside of molesting young boys which was done in secret and not openly. Sandusky was never, as I understand ever interested in having sex with other adult men, only in having sex with children who happened to be male. A male pedophile who prefers having sex with female children is none the less still a pedophile and just as sick, twisted and evil.
Barring openly homosexuals from leadership positions would not have prevented someone like Sandusky from doing what he did as he was not an openly homosexual man who had sex with other adult men. He lived as a straight man, a pillar of his community, someone well respected in his community and someone that even his neighbors and close friends, some who are deeply religious, had no idea of his perversions, yet he was someone who secretly preyed on vulnerable children for years.
