South Park's take on Dawkins and Harris

Trey Parker and Matt Stone have published a great episode of their "South Park" series in which Cartman is frozen in time and revived 500 years in the future. In this future, Richard Dawkins and Sam Harris have won, and Atheism is the dominant ideology. But now, rival alliances of atheists are killing each other. Parker and Stone are making the point that it's human nature to kill each other, and religion is just used as a way of picking teams.

True. But I think Harris would respond by saying that the warring atheists in the South Park scenario would be much more concerned about risking their own lives in attempting to kill other, since atheists do not believe in a certain afterlife.
