I was a cheerleader at Florida State in the early 90's
(now I know some of you do not consider it a sport, just try it, you will not last)
I came out/ got outed my last year(94), and it was really not a big deal, but I was a cheerleader. Most people have a preception of male cheerleaders as gay. That said it caused me to meet the other gay athletes (and one coach)within the athletic department. It also helped that I was very close the the president and I was in student goverment.
It was along time ago.....there are many more out gay athletes
Meanwhile cheerleading has gotten very straight among the guys.
