I don't believe it is over-exaggeration. Archbishop Silvano Tomasi in September last year spoke at the UN on behalf of the Holy See and said that the majority of those who committed abuse should not be considered paedophiles but homosexuals who are inclined towards sex with adolescent males.
The link still goes on and the Vatican still propogates that the contributing factor to sexual abuse is homosexuality.
I think he might be correct, but from a
cultural standpoint.
We live in a culture (Western Culture) where men traditionally married women. We also had men that were not interested in women, and interested in men. It was abnormal,
culturally, for a man not to be married, and for a man to be attracted to a man. It was also considered to be a manifestation of sin.
One way to avoid that has been to enter the priesthood. There is no abnormality with a priest not being married. There is also, on a spiritual level, to fight the temptation of the "sin."
Now, that doesn't apply to the majority of celibate clergy, but it does some.
The priesthood, for some, becomes a hiding place, from both culture and perceived sin. The celibacy aspect can attract some gay men, but not a contributing factor to "gayness."
