He is showing that you can be a guy or a girl and have the opportunity to participate in the same activities. I don't know if he is a great cheerleader or great dancer but when Utah played at BYU last year he was cheering in front of the West side and he seemed like he was doing the same exact cheers as the girls. He also seemed to be enjoying himself.
I don't have any problem joking about the videos of him but I also don't have any issue with him being a cheerleader if he is good enough to make the team.
