Please get to know the sport before you trash it.
Cheerleading takes the utmost psychical and mental skill. You have to stay concentrated and focused to know what you're going to do next. You have to be prepared for anything coming your way. My gym told us, if you're going to be a sissy, get out. Most uptight and preppy cheerleaders I know, stink. You've only met the school cheerleaders most likely. Once you join a regular competing team, you'll learn what the sport is really about. Once you join you won't want to quit. Your team becomes your family. The gym becomes your home. You breathe, eat, sleep, and talk cheer.
Don't listen to those stereotypes on TV. They wouldn't know cheerleading if a flier came down on their face.
P.S. : Cheer is my life. Before you trash it I'd like to see you juggle cheer practice 5 days a week, 3 hours a day, while doing homework, going to school, and trying to get the right amount of sleep. Also, on top of that, pay $2000 for a year while your father is the only one working because your mother is sick, and barely getting by just so you could do the sport you truly love.
Long speech, but I just don't like people trash talking about things before they even try it.
