But I'm sure you realize the problem is more complicated than that. With the shortage of vocations over the last few decades, bishops feel a lot of presure to re-assign a priest who has engaged in inappropriate behavior, has serious addictions to alcohol or drugs, has other mental health problems, etc. That doesn't excuse anything. I, personally, think the bishops who coverup these criminal acts belong in jail.
Do read Goodbye, Good Men>, due out about now. Major seminaries have been turning away those who are orthodox in favor of the loony left. Those seminaries that have been turning away homosexuals and those weak in faith and accepting the orthodox and devout are flourishing.
Youth really are idealistic (and I say this as someone who doesn't much care for the young -- they're too exhausting); vocations (it seems to me) dropped when the Church stopped demanding everything -- do your own thing, have your own apartment, dress like everyone else. I think the Palestinian suicide bombers -- and/or those who recruit them -- have more sense (and I am staunchly pro-Israel; I think they're horribly wrong, but not necessarily lost -- remember C.S. Lewis in the Narnia series -- intention counts for a lot).
Ask everything of youth and you'll get it. Ask crap, and you'll get that.
