I think you would be hard pressed to get them to name five differences between the two sides.
Really? I'll hammer some out now, as related to me through Protestant propaganda:
1) Protestants believe that they are "saved" through faith exclusively. Catholics believe that your actions have repercussions.
2) Catholics have saints and the Pope. Protestants have, uhhh... a string of televangelists, which at least doesn't include Ratzinger, but that's about the only good news there.
3) Catholics baptize babies. Protestants wait until they have had ample time to brainwash the child before asking them whether or not they'd like to be forcibly held underwater. If the brainwashing was successful, it's a yes.
4) Protestant "mass" isn't called mass, and it's slightly less ritualistic than a Catholic's Sunday morning.
5) Catholics drink REAL WINE for communion, and Protestants (Baptists, at least) roll with grape juice. Yeah, I was planning on getting drunk off of a third of a shot of wine.
OK, yeah, you were right. I really degenerated towards the end.
Still, that #1 is a big deal to a lot of folks. I remember it being hammered into my fragile little brain early on.
I brought up ol' Mitt's magic Mormon underwear to my parents, who would follow the GOP off a cliff. It definitely created some cognitive dissonance for them. This especially intrigues me because I vividly recall a Sunday School lesson from when I was around 11 or 12, titled (no, seriously) "Why Other Religions Are Wrong", which seemed to feature the LDS/Mormons. Sometime between then and graduating high school, things went terribly wrong for me. Literally, went to hell. According to my parents.
