Ah, yes. Catholics. Those who follow the great and ponderous teachings of Cathol.

What a silly question, sadly I have come across people who actually felt this way. When confronted with such ignorance, I never know whether to laugh or pat the person on the head and tell them everything will be okay.
In reality this question is rife with real issues and stems from divisions between Catholics and Protostants back in the early days of the split. Back in those days most Protestants actually considered the Pope the Anti-Christ. Some still do. However, most people who believe this do not do so because of the complexities of Protestantism in the early days. Most people think this because they are ignorant and have no real desire to learn or grow in their faith.
