Ok, gotcha. Sorry for the mis-understanding.
As far as them making decisions they cannot make, I do think that judging the Pope as an anti-pope is a bit extreme (unless the Pope were to commit undeniable heresy or if he was not Catholic). Outside of that, however, we are free to judge people's actions. If a bishop says that women can be priests, I'd label that as a heresy. My real thing is that if a person commits an undeniable heresy, wouldn't that exclude him from the Catholic Church?
