People make far too many stereotypes. Not all extreme sport "types" are jocks, not all traceurs who compete are jerks, not all traceurs who train properly are disciplined and respectful, etc etc.
Media perpetuates these false truths and they spread like wildfire.
Competition can be horribly done, or it can be a beautiful thing - all dependent on the mindset of the individuals involved. I think the most fun I've ever had in a competition was a rock climbing competition, where everyone was really supportive of each other and we all pushed ourselves to do really awesome things. Of course, we all pushed for safety but that's because we all normally train with safety in our daily lives. At the same time, I'm seen some disgusting competitions where the only issue was who will win! Needless to say, the participants in those competitions were no people I would enjoy friendship with.
Going back to the X-Games reference, I wish I could hang out with the likes of Tony Hawk, Bob Burnquist, Danny Way, Shaun White, etc. They're all probably a bunch of awesome guys - do you think they perpetuate the notion that skateboarders are all punk kids that love disrespecting people? NO! These people fight to give skating a proper name, just like we all struggle to keep parkour in as brilliant a light as possible. If a parkour competition was done right (I enjoy the idea of a ninja warrior type competition!) and it had the right competitors (once again, I'd love to be a part of it

) then it could be a huge push towards stabilizing parkour as a deep discipline and art form, not just a sport where crazy kids jump off things

Please share your comments/concerns about my opinion, I'd love to hear them all!
