I would not discount it being a warning shot for these groups' leaders -- get on board for Obama NOW or else. The abuse is mostly men molesting boys, and the MSM does not generally go out of their way to focus on homosexual abuse.
OTOH, I think it more general politics than anything related to stifling comment about Obama's gay marriage position.
Lastly, I think that some communities' leaders have been co-opted by molesters among them. I think that the gays among them work tirelessly to remove from leadership any rabbi who might seriously threaten them, and promote any rabbi who is willing to cover for them. The game is not limited to the Ultra-Orthodox. The Sandusky case at Penn State stands out.
“The abuse is mostly men molesting boys, and the MSM does not generally go out of their way to focus on homosexual abuse.”
Given the non-stop coverage of the Catholic Church scandal, you can’t ignore the obvious. They ignore gay rape when it is done in lib circles (public schools, Girl Scouts - who have no ban on gay scoutmasters) and pour it on when it is done in the “enemy camp” (Catholic Church, Boy Scouts, and now I suspect Orthodox Judaism). The Orthodox method of dealing with this was reported quite a bit when the Church coverage was at its peak.
