Far from it. He's a very well respected priest in the Catholic community (FAITHFUL Catholic community, not the cafeteria kind) and has done a LOAD of good stuff for the pro-life movement.
I have never heard Hannity claim to be some sort of Catholic expert, a guru, nor have I ever heard him place himself on a pedestal concerning his religion.
Well then you haven't been listening. For years Sean has been calling himself a "devout, practicing Catholic". If you don't follow the core tenets of the Catholic faith (for instance refusing to believe the Church's stand that contraception is intrinsically evil), then you can't be a "devout, PRACTICING Catholic". Just going to church on Sunday does not a devout Catholic make!
Like O'Reilly, I've heard Sean make troubling statements about artificial birth control being okay in some situations, and this is NOT what the Church teaches.
Moreover, Sean HAS worn his Catholicism on his sleeve. If he's so vocal about his faith, it's certainly legitimate to call him on it when he errs. Especially when the person erring is a public figure who can mislead people into believing erroneous things about the Catholic faith.
An elderly man walks into a confessional. The following conversation ensues:
Man: "I am 92 years old, have a wonderful wife of 70 years, many children,
grandchildren, and great grandchildren. Yesterday, I picked up two college
girls, hitchhiking. We went to a motel, where I had sex with each of them
three times."
Priest: "Are you sorry for your sins?"
Man: "What sins?"
Priest: "What kind of a Catholic are you?"
Man: "I'm Jewish."
Priest: "Why are you telling me all this?"
Man: "I'm 92 years old .. I'm telling everybody."
