Do you consider Cheerleading a sport?

Everyone always asks me what sport I'm in. My reply is cheerleading. And you know what their response is? Cheerleadings not a sport! I'd like to know if you guys think it is a sport, or not a sport. I'd also like you to tell my why you think what you think. It bothers me how people don't recognize it as a sport. We work just as hard as the football players, baseball players, wrestlers. etc. They lift weights, we lift PEOPLE!!! Cheerleading is indeed, a sport!
