I think the homosexuality aspect of the Catholic child abuse problem comes from segregating the sexes - not necessarily as the only cause, but that system provides the 'heaven sent' opportunities for homosexual child abusers very effectively. It should be noted though that the problem consists of more than sexual abuse. Violence and sadism is much more common, and whilst that can be sexual in origin, it isn't necessarily so.

Interesting to note that both the Marquis de Sade and Leopold von Sacher-Masoch were raised as Catholics..
