Biologist Richard Dawkins made a two-part documentary which attacked religious faith, featuring several religious figures (including the recently outted Paul Haggard).
Filmmaker Rod Liddle made a rebuttal claiming that atheists can be just as fundamentalist as their religious counterparts and that it is not religious faith per se which is at the root of all evil, featuring Richard Dawkins himself among others.
Both BBC (Channel 4) documentaries are available online. View them; discuss.
