That's true for Judaism, Islam, Buddhism, Christianity, etc. That does not mean they should escape valid criticism.
The difference is that when other communities are criticized by the actions of a Mullah or even the abandonment of children the backlash is an accusation racism. But one Priest makes a stupid statement and suddenly it;'s an indictment of the entire Church. And trust me, I have some issues with the RCC, but the double standard is ridiculous.
