At least BMX racing is an actual sport. The fastest person wins; I dont have much problem with that. Its all the flippy-dippy, synchronized stuff where one competes for style points while wearing make-up, costumes, and a smile that have no place in the Olympics.
Just because something takes incredible athletic ability does not make it a sport. Have you ever watched the best tap dancers in the world? They are seriously badass. Still, tap dancing aint a sport.
