Why can't American Rednecks understand catholic are christains?

I think it has to do with a lot of ignorance, and a lack of a history or humanities class. Catholics were the first Christians. Many protestants, along with others get a bad taste in their mouth when even hearing the word, 'Catholic', so they would never want to associate themselves with it. Even a the Apostles Creed, a Catholic prayer, with the word catholic in it, is used by most christian churches. All in all, its a shame. Catholics among other Christians all have the same goal, and we should work together to accomplish that goal.
