First of all, most priests, the priests who would have access to teens and children, are hardly "sequestered." They live extremely public lives, probably much more so than most of us. In the same vein they are not "confined" to the company of other priests, exclusively, nor are they somehow socially isolated, as your words imply. On the other hand, those priests who do live a cloistered life obviously lack the access to teens and children.
The idea that "many" priests are "pedophiles" is an outrageous slur that cannot be born out by any evidence.
Thank god my experience growing up and being educated in the Catholic church, as well as the experience of the many others who shared that experience with me, bears so little resemblance to the outrageous image you have.
God bless you. You speak for many of us.
The outrageous image I have witnessed.
