That is simply not true. As many RCs can tell you, historical catholic theology certainly does bash another religion, damning all to Hell if they are not in submission to the pope, though modern RC teaching redefines that.
You are not correct.
I remember reading that. Seems there have been many threads about being Catholic is only way to get to heaven. Someone even posted that they want the whole world to be Catholic. I remember asking the poster if that meant he/she wanted a one world religion. I was shocked when the reply was yes.
