Is this somehow news to you? Are you really so clueless as to not be aware of the basic differences between Protestant and Catholic theology?
That of course does not change the fact that the historic position of the Catholic Church is young earth creationism.
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.
