The last few popes have been relatively progressive, especially compared to most of the Protestant offshoots of the Martin Luther/John Calvin types. I'd recommend checking out the papal enclyclicals. There's a bunch of them that read borderline Marxist, like Rerum Novarum.
Now that ive said something nice about them, still, the Catholic Church is an organization that does protect its own pedos from punishment, which isn't unique to the Catholic Church, still fuck the Catholic church for that.
