A little ways back, Christopher Hitchens fielded questions for 30 minutes from Reddit.com users, answering any and every question they threw his way. What historical figures, events or books have been underemphasized in American public education? Has the Iraq War (something Hitchens supported) had a positive or negative impact on Islamic extremism? What do socialism and libertarianism have in common intellectually, if anything? Other figures interviewed by Reddit users include Richard Dawkins, Noam Chomsky, and Ron Paul.
