To listen, go here. All in all, a very fair interview, I thought. Near the end, the interviewer remarks on the surprising number of emails sympathetic to Benatar's position. This further supports my belief that the inherent logic of the argument strikes a chord with more people than one might imagine, given the sometimes vociferous reactions issuing from the pro-natalist camp. As with religion, I think there are lots of people who passively accept the culturally embedded notion that 'the species must endure', simply because they've never been exposed to a coherent expression of the alternative. But once they hear it, bells go off. Seems promising.
Thanks to Chip for the ref.
