Besides the immense amount of abuse that has happened in the Catholic Church, the Church has a sordid history of covering up and protecting priests so that they can continue to abuse for decades. So there's that.
There's also the fact that the Catholic Church holds itself up as a paragon of morality and truth, and expends great effort in having answers for everything that do not admit alternate interpretations. For such an institution to be guilty of sexually victimizing literally thousands of children, allows the Church to receive back from millions of people a focus for the rage the Church has created in them by inflicting its arrogance upon them.
You see, millions of people feel that if the Church actually deserved its claims of holiness, such abuse would simply never happen within its ranks, and if it did, it would be treated with the utmost honesty and protection for the victims. Instead, the Church wants it both ways - to be the mandated for all spiritual practices and decisions for the entirety of the human race, and be allowed to escape with a shrug about being just as human as anyone else when it is found to have committed, and protected, crimes of atrocity.
The great unwashed see that as profound hypocrisy.
That the Church then responds by spinning and minimizing its abuse statistics and denying all arrogance in the face of this uproar doesn't exactly help things get any better.
Such a society has no moral standing to point any fingers at anyone else and then complain about hypocrisy. God will judge us more severely than the Nazis if we don't repent.
Do you have the same feelings about the immense amount of abuse that occurs in public education and the indifference of property tax payers who blindly support same?
