Takes some really high level athletic abilities, is great for fitness, there are some really dedicated preformers. What is the problem?
That they used the sacred words "Martial Arts"?
So What?
Performance, Meditation, Fighting, Fitness, Self-confidence, etc.
Many reasons to train, many different approaches that match them.
Everyone that I have met that did that sort of stuff knew and claimed that this is not for fighting or self-defence, it is for fun and for show. There is no deception at all in what they do, they are perfectly honest about it.
Isn't this sort of like if Tour de France guys started complaining how BMXing is not biking, has no real value and is all for show cause they can't really race comparred to racers, and showing it on tv hurts the image of "real" bikers?
