That site doesn't explain "the differences between Protestant and Catholic theology," it contrasts "Catholic tradition" and "the Bible." It says the Catholic Church violates the teachings of the Bible in ways that are sins and that anger God, and it illustrates the point with a crude drawing of the Pope in league with Satan to promote a perverted Bible. It's vile anti-Catholic bigotry, and you should be ashamed of yourself for defending it.
Surely you didn’t expect any trace of honor from GGG.
