Thanks for the heads-up; I'll give it a watch if I can find it :-) Just wanted to add that Richard Dawkins made a documentary in which he countered misinterpretations of "The Selfish Gene" called "Nice Guys Finish First":
In the opening scene, Richard Dawkins responds very precisely to what he views as a misrepresentation of his first book The Selfish Gene. In particular the response of the right wing for using it as justification for social Darwinism and laissez-faire economics (free-market capitalism).
