Craig Newmark has been down on debate for some time now (here's a recent comment on high school policy debate). I never took part in debate, except with my friends over a few beers, and we certainly never carried on like this.
OK. I shouldn't judge college debate based on a few minutes on YouTube. But it's great satire.
The next time I get harshly criticized at a seminar, I think I'll moon the criticizer like one of the debate coaches did. That'd be a piece of work.
