It's been my experience that MANY members of the religious orders in the present times are people that have ties with or grew up in/around the eastern bloc. The church wasn't so castrated back then, they actively fought against the oppression of the communist regimes. A lot of these people, then, can see what is on it's way if we continue down this path, and they do not like it.

That and the current mass infanticide (abortion) is possibly one of the greatest crimes against humanity in human history. They know this.
