What is the difference between Catholics and Protestants?

Catholics are real Christians, Protestants are sinners in a made up religion which was created by an alcoholic, nymphomaniac glutton who wanted to suit himself. Lutheranism is one of the many, many offshoots of Protestantism. This is what happens when someone decides they don't like their religion so they're going to set up their own, when they eventually do set up their own religion, people in said religion decide that they don't like THAT religion and then decide to make their own variation of an already shakey religion. This is why there is dozens of different types of Protestantism.
