I am not a Catholic, and I have never been convinced that priests should not marry. But it's their religion and they can make whatever rules they want.
However, I see no connection between "banging little boys" and "allowing priests to marry".
Are you married? If you were not married, would you want to "bang little boys"?
Seriously, your post makes no sense, unless you meant allowing priests to engage in "gay marriage" with little boys. A better response would be this: "Know what might keep priests from banging little boys? Weeding out homosexuals from the seminaries. Just a thought".
The dirty little secret is that this is the very reason why this doctrine even exists. Celibacy was never a requirement of the early church and it wasn't until the middle ages that Rome declared it law.
Wonder why?
