This shouldn’t surprise anyone. Way too many churches became simply cheerleaders for government social spending in the 60s and 70s and others turned into weekly “feel good” sessions that simply tell you how much God loves you. Any sense of obligation went out the window. The religion becomes meaningless and when it does, why should anyone want to go to that type of church?
I agree. Also, there seems to be an inevitable trend for very well-off societies to turn more secular. And, the Catholic Church in the US didn't do itself any favors by attempting to minimize institutional damage by denying the priest pedophile scandals.
That's what drove me out of the Catholic faith in the late '70s. It was becoming a hotbed of leftist dogma, especially with the surge in "liberation theology" in Latin American countries. I wanted no part of it.
