you know what super, duper annoys me when this topic comes up? when people quote articles about cheer injuries as justification that it's a sport! I mean, come on, people. you ask/desire legitimacy, and all you can come up with, is well we can break our necks, so therefore we are a sport?
and the point is, MOST of the injuries cited occur in highschool and/or sideline cheer, which any allstar cheerleader is quick to say it isn't the same thing.
There are many, many things that prohibit the 'legitimacy-is-ing' (i know i just made that up), and frequently, those that defend the 'sport-ness' of the cheer world, contradict that with their actions or comments. Sorry, feel free to tear me apart, but that's my rant!!
