Good video but did you miss the part that said:
"DON'T WATCH THIS VIDEO. I'm serious. This message isn't a hack (I'm the guy in the video), and it's not a ploy to get you to actually watch it (reverse psychology).
It's just that there's a hole in this argument big enough to drive a Hummer through because of an assumption I didn't realize I had (isn't that just the way with assumptions. . .), and the argument has been UPDATED to address that hole.
So instead of watching this old, tired, hole-y video, go watch the NEW, IMPROVED version at http://www.youtube.com/watch?v=mF_ana..." etc
Here's the new improved video with answers to all the questions and criticisms to the original video.
