I would have to say those that worship the Devil. The Moslems and the Jews are trying to worship God, but they are in error. The same could be said of other religions. However, what could be more evil than those that not only reject God, but choose to worship Satan instead?
I wonder how many of them actually worship the evil one or are just atheists who just wanted to add extra insult to their God-mocking ways?
It's like the Church of the Flying Spaghetti Monster or whatever that is.
SO annoying (at the very least). When I was in college, people would make references like "God, Allah, the Flying Spaghetti Monster, whatever" in class.
What a mockery, comparing some Internet meme to religions with rich traditions and millions of adherents. Ugh.
