In the eyes of those who hate the Catholic Church it can do no right. No matter what the Church does or says something must be wrong with it. This hatred is not merely human ego, although there is a lot of that, it’s also demonic, as sententia cited.
G. K. Chesterton wrote that once a man stops attacking the Church and starts to treat it fairly he finds himself attracted to it. This is true for many people, and I think people can sense that that’s true which is why they fight so hard against the Church.
They even say that people become Catholic because they become attracted to its sensuality–the sights, sounds, and smells, as if it were only that. But, it goes much deeper than that, which they also know (even if they won’t admit it), and they simply don’t want to be Catholic and have to submit themselves to the Church’s authority. Not when they can set themselves up as their own pope, believe what they want, and do whatever they want.
