This is actually quite funny, with just a hint of supercreepy. The very thought of anyone organizing atheists into an army bent on world conquest is completely laughable. Sorry, we just don't work that way. Not to mention that most of us, Dawkins included, are ardent pacifists as well.
But then they warn the Christians to get their sword and fight off the evil atheists. Um, what? Is this more of that Bush era "strike first" kind of thing? It's more than a little creepy that there are Christians out there who might take this video seriously.
Let me make one thing clear: I'm not fighting a war for Richard Dawkins or anybody until I get my own giant fucking killer robot.
