Religion

The sexual proclivities of the Catholic church have been well known for hundreds of years now. Chaucer alluded to it The Canterbury Tales, and their were other authors who wrote about the inability of many in the clergy to keep their habits down. Everyone knew that a lot of them couldn't keep their vows, but it was accepted because openly questioning the church about anything could get them in a lot of trouble. The church doesn't have the power it once had, so people aren't putting up with it anymore.

If the Catholic church wants to survive, they're going to have to do some major reform, but that will piss off the hardcore Catholics who love all the church's medieval structure and practices. The future of that church is in serious jeopardy, at least for the churches in Europe, North America, and Australia.
