Now, this is interesting, you are telling me that you'd say to your daughter "Honey, you're too fat to be a cheerleader, maybe you shouldn't do something that you would potentially like."? I was (well, still am...) fat and unathletic, but my parents still encouraged me to go out for sports. I sucked at wrestling, but I kept at it thanks to their support. If they would have discouraged me from wrestling because I wasn't very good, I would have probably quit after 8th grade; I would have never got to experience the pride of wrestling and qualifying for state and experienceing the walk-in (which was AWESOME) and the brotherhood of wrestling.
My parents would never discourage me from trying anything. Heck, they would have supported me if I went out for cross-country! Discouraging a kid from doing something they want to do (especially because of their looks!) is wrong, wrong, wrong!
At Caney, most of the cheerleaders were girls who couldn't make the basketball squad, except for one who never tried out for the basketball squad, she loved wrestling. She may have not been the best-looking cheerleader on the wrestling squad (she was a little hefty, too), but I appreciated that hug on the podium at regionals from her more than I would have appreciated it from any of the others.
