There has been a lot of talk in all the usual places about whether Billy Nye should debate Ken Ham. Some prominent people think it’s a bad idea. I see where they’re coming from, at least as far as exposure is concerned. I bet a lot of folks will watch the debate and figure the differing positions are equally valid, and it may be true that Ham has more to gain from the debate than Nye. But, I can’t help myself from thinking “So what?” Think of all the times a prominent scientist/atheist has debated a creationist. Can we honestly say that the consequences have been bad for the public understanding of science or education or rationalist movements?
