He says, obviously in the name of satire, that the entire Catholic hierarchy exists, and has always existed, for the sole purpose of pedophilia. Again, that's like saying the entire hierarchy of Islam was created for terrorism, or the entire Mormon one was created for plural marriage, or the entire Southern Baptist one was created to destroy science. It's insulting to thousands of past and present Catholic priests who've never engaged in pedophilia nor concealed the crimes of others and, given that the Roman Catholic Church was THE Christian Church until the Great Schism, insulting to every Christian priest from Peter down till then. I suppose to that extent I can be personally offended as a Christian rather than just generally as an intelligent and (hopefully) fair minded person. And, just to be fair, it was equally insulting (but more original) when South Park did it several years ago.

Even for someone who's frequently gotten in trouble with friends for tarring with too broad a brush this is extreme.
