My one question is why did he perpetrate the misinformation?
It's hard to conclude that it wasn't deliberate. And if deliberate, then why?
Perhaps he's a genuine professional IDer, looking to sap more donation money for the Discovery Institute or another non-profit.
As the environmental advocacy community of Sierra Club, Greenpeas etc. have demonstrated, there's lots of money out there. And the Christian community has remarkably few national non-profits living off it. So the pickings are ripe for those dishonest enough to separate Christians from their money in return for emotional issues confronted.
