Personally, I think there is some truth to the idea that the "free love" movement helped provide cover for some pedophile priests in that it created an open environment for considering alternative sexual practices. At least this was my experience. I think it created an environment in which people could say, if church teachings on sex outside of marriage are being challenged, could you not also challenge other sexual mores? I think some pedophiles try to rationalize they're behavior because they don't want to accept that they are doing horrible things that will cripple their victims forever.
I do believe there was a general pushing of boundaries that was encouraged in the 60s and 70s that created some very ugly side effects. And pedophiles used this situation to rationalize their behavior.
But as I say, I don't think the idea that hippy culture was invading the church explains the problem. The real challenge to the Catholic Church, and all of us, is the question: Why was this not stopped by those who knew it was happening? In my opinion, it is a lack of individual courage and morality that is the real scourge within the church and elsewhere. These are the revelations that I find just astounding. The police, other priests, teachers, etc. many people in these positions knew what the priests were doing, but they did not stop it. And that's not because they embraced some notion of free love that encompassed pedophilia. It's because of moral cowardice.
I hope that in mainstream society today as compared to when I was a kid pedophiles have a much harder time operating without being stopped. Not sure if there's reason to be hopeful or not.
Work like you don't need the money;
dance like no one is watching;
sing like no one is listening;
love like you've never been hurt;
and live life every day as if it were your last.
