The way it's supposed to work is this way: The techniques demonstrated are supposed to be authentic in that they can be used in a real defensive/combative situations. In other words, they are supposedto be "street-wise" tactics. However, these types of techniques are not appealing to the "untrained" eyes of the judges and largely the spectators who cheer wildly for stupid so-called self defense techniques that would get you killed in you tried to use them in a life or death situation. As a result, the "theatrical" style of self defense wins out. Here is the worse example: a seven year old child, beating the hell out of a 200 lb man using theatrical self defense. A ligitemate self defense situation does not stand a chance here.
What blows my mind is that these judges (and the spectators) cannot separate fact from fiction when it comes to self defense. The self defense category at these tournaments have absolutely nothing to do with self defense. It's just another way for promoters to make money. But then making money is the American way, and we can't blame them for wanting to support themselves and their families. (forgive any typo's in this message)
