This young woman is a performer, a great one at that, who has feelings just like you and I. Drum corps is an educational opportunity and should continue to be so. As a person who claims to support drum corps, this is not the best way to represent yourself as a person or as a fan of the activity.
Size 2 or 20, she is still a beautiful girl doing a great job fulfilling her role as a performer and a Cadet.
Shame on you.
