84% of people on Earth belong to the first group, 100%, at one moment, belong to the latter. Spans all kinds of cultural and political beliefs. It has nothing to do with the comparison you are drawing. There are many in that group that share your political concerns. Which again, is fine. It's simply about being inclusive to large groups for ticket sales, which doesn't seem odd, at all.
The day is also about 4 groups, so it's not as exclusive as some may think. Faith, Family, Band, and Youth Football day. There are folks offended by youth football, as well. They're even trying to ban it, in Massachusetts.
I may think that Dance and Cheer day may objectify, and push a stereotype. But if the kids like it? Good for them.
