You know, it's usually the girls doing the inappropriate moves- obvious issue of their being more girl cheerleaders aside- and not the boys? Boys aren't choreographed in a lot of hip thrusting, thigh spreading, booty popping as the girls are..Even in a coed routine, where there are more guys, there are less moves done highlighting THEIR...bodies as there are moves for girls.
Actually- I do think dance moves have gotten more risque as the years have gone on..If I showed someone what some of these junior, youth and mini teams do (All minors, keep in mind. Heck, most senior team kids are minors!), their eyes would bug out. Sad to say, but this sort of thing IS how stereotypes develop. WE think it's 'fierce', but I also wonder how many world-winning routines had girls doing REALLY inappropriate routines. Or even semi-inappropriate. Rays, WC, and even TG (who can get a little out-there with the uniforms), have all won worlds multiple times without anybody really emphasizing anything inappropriate. 'Cause maybe you don't NEED to in order to have a good dance..or win.
