I'm assuming you are being funny, but just in case you aren't: President Bush was a cheerleader his senior year at the Phillips Academy in Andover, Massachusetts. Look it up.
Seriously. There are plenty of male cheerleaders. Plenty. Tons. Always have been. To repeat your question: What planet do you live on?
I am talking about high school. I repeat I never once saw a male cheerleader in the SOuth our Midwest. It must be more prevalent in other parts of the country.
