First, celebacy itself does not alter some one’s ‘potential partner pool’. If I’m an adult female w/adult heterosexual orientation, my ‘potential partner pool’ does not include immature humans of either gender.
So, for Potential Priests, unless they have a ‘potential partner pool’ that includes immature humans of either gender, ‘celebacy’ requirements will not increase or decrease the incidence of child molestation among the priesthood.
For those who have a ‘potential partner pool’ that includes immature humans of either gender, partnering up w/immature humans is against the ‘statute’ law in all 50 states (and most nations as well), so I can’t see where additional ‘no, you can’t do that’ instructions from their employer would serve additional restraints to their actions.
Abandoning the celbacy requirement may be a ‘good’ thing to do for other reasons, however, don’t for a moment believe that it would alter/decrease the incidence of molestations among the clergy.
And, of course, gender preference for adults has nothing to do with gender preference for minors. (many cases of males w/wives who molest young boys - John Wayne Gacy for example). And, while we’re on that tangent, let me ask the hypothetical Powers that Be who think screening out males w/same gender sexual preferences will solve their crisis - um, what about the little girls? they’re far more likely to be molested (according to Justice Department figures) than little boys, screening out homosexual males, wouldn’t do a thing to protect little girls (it also wouldn’t necessarily protect little boys, either, but… )
