Firstly, paedophilia is very rare in the abuse committed by Catholic priest....even rarer than paedophilia in the general public.
84% of the abuse was committed by adult men against teenage boys and youths.   This is simple homosexual assault of minors.
Studies say that there are very high numbers of homosexuals in the priesthood, that there is a strong homosexual subculture in the seminaries (as Joe has noted)....56% of ordained priests interviewed agreed that this subculture existed.

Does anyone seriously put up the suggestion that heterosexuals are attracted sexually to their own gender?
