Jim the point I was trying to make was that although the Catholic Church has ruled on Pederasty at least since the second century, other cultures under other religions have at least tacitly accepted/encouraged/condoned such practises. The prime example would be the Ottoman Empire and many other ancient cultures. The Catholic Church may have failed in stamping out the practise within their own clergy but their public condemnation of such abuse goes back centuries.
A similar level of condemnation in Islamic cultures is not so obvious.

Some of your criticism of the way the Catholic Church handled abuse may be justified but it needs to be seen in a much wider context. Catholicism does not have the monopoly of black sheep.
