personally, i could care less if curling is a sport or not, prolly tons of faithful practicers and fans of the event, but it doesn't belong in the Olympics. no matter how tainted the Olympics are by sponsors and politics, the fact remains every sport I can think of (summer or winter) involves a high level of athleticism. the variety of sports all depend on the most pure forms of athleticism--running, jumping, and throwing.
having read dozens if not hundreds of threads regarding the legitimacy of athleticism of football (american), baseball, and other sports, it seems the general consensus is that basketball is the most athletic of the 4 major sports most watched in the US--necessitating running, jumping, and throwing/shooting. you can't be a Tony Saragusa (sp?) or David Wells or some other unathletic type and expect to succeed in the NBA. having watched almost all the broadcasted curling on the NBC networks this Olympics, this is the analogy i draw when i see unathletic individuals participating in the most pure of athletic events epitomized every 2 years (winter-summer alternate) in the Olympics.
having watched some exciting matches the last 2 days, i have no doubt an exceedingly high level of skill is needed, and years of dedication needed to learn and perfect the craft, but that doesn't merit a spot as an Olympics sport. this is the same reason I don't want to see chess in the upcoming summer events (being petitioned last i heard). x951's video game analogy follows this same "skill" logic
