I have no problem with the Roman Catholic RELIGION, it's some of the guys running it that's a problem. I also think the cover-ups are due to....
* Embarrassment, shame & denial for most of the RC leadership.
* They have a bit of a clergy-shortage and can't afford to lose any more (the fact that the solution to that problem involves relaxing some sex/marriage based rules, women clergy and optional celibacy completely escapes them).
* A minority of leaders are probably evil corrupt kid-fiddlers who think "Going Roman" in the "Roman Church" involves some good ol fashioned "Roman Pederasty".
In regards to this guy in Brazil, I get the impression that some guys start cults for the SOLE PURPOSE of indulging in their perversions. I feel the same about many of those FLDS groups. Warren Jeffs and his ilk just wanted a scheme where they, older & middle-aged guys, can get themselves some tween/teenaged girls. Why else would they often kick out all those teen boys from their cults? The whole point of the sect is "old guys marrying a bunch of young girls".
