I mean, possibly, but yeah “heresy” isn’t really a big deal in the modern sense. Like, Protestants are heretics. Nobody really cares at this point.
This guy hasn’t been defrocked, just removed from the bishop’s seat. He’s still a priest. If he goes and starts a different (non-Catholic) church, he’d be dismissed, probably excommunicated, but that’s pretty rare I think. And regardless of what he thinks of his boss, his whole life is basically being a Catholic priest. I doubt he’ll leave.
Who’s the “other guy”?
Literally who are you advocating for? Who do you think will apparently fix the state of American democracy in 2024?
