Glenn Greenwald and Sam Harris made the news this week, but I think the Chomsky-Hitchens debate is still the classic text in this genre on the appropriate secular humanist response to the dangers of, and relationships between, dogmatism and violence.
And yes, Harris actually challenged Greenwald to a carton contest. Maybe Greenwald should take him up on it?
I'd pay to see a Chomsky-Dawkins debate on this, but a Greenwald-Harris debate? Meh.
