I'm actually a member over on parkour.net so I had seen this post awhile ago. Even though this stuff is worth knowing about, the activity we do, that we enjoy, running over things, getting from point A to point B, its all still there. I'm going to go home and work out today knowing full well David Belle has labled parkour as sport.
The people that are getting their worlds rocked right now are the ones that take parkour too seriously. By that I mean not seriously training hard and wanting to get better, but taking parkour and trying to transform it into some quasi-religious spiritual thing when its not. David has openly admitted that it isn't a complete discipline but people follow it anyway beliving that theres some sort of life truth in living a simple life and getting from point A to point B. Now David has up and turned their religion into a sport. How dare he! Seriously, I respect David because he's doing whats best for himself and we should follow his example by doing whats best for ourselves too, which right now, is doing what we have been doing and practicing the old parkour.
