Its amazing how people are allowed to make blanket judgments about Catholicism and its priest based on the fact that some disgusting people have become priests.
Trouble is that it's not the paedophilia thing alone. It's the extreme abuses of children in the Magdelen Laundries, as others have said it's the extreme wealth possessed by the church in comparison to the poverty of millions, it's the integral profound sexism and utterly rigid inflexibility of the organisation, it's the intense manipulation by inculcating guilt in people and then playing on it. Plus the inescapable feeling that they're hiding a massive amount of information, plus an extremely oppressive history.
There are many intensely autocratic and inflexible institutions with bullying problems (the military forces not all that long ago) but the Catholic church claimed that they represent the teachings of Jesus, which are amazing, and that the Pope is the infallible representative of God on earth.
I think when you put all that together along with the covering up of so much evil, it's not surprising that the Catholic church attracts some pretty blanket condemnation.
Longstanding monolithic cultures are rarely pretty but the Catholic church claims great deal of moral high ground. Revulsion at what's been done as opposed to what's been claimed was always going to be intense.
