Regarding the term "genre" I have no real problem calling it a genre, if that's what you want. It's a misuse of the term, but who cares? I'm not hung up on it as long as I know what you mean when you say it. That said, if you're using "genre" to refer to a unique and distinct style of martial art, I think you're mistaken.
BJJ existed as a martial art before BJJ competition came about, just as Judo, Muay Thai, TKD and Kyokushin Karate did. In all of these cases, the competition continues to shape the martial art, but a martial art it remains as it was prior to the competitive elements.
MMA, unlike BJJ, Judo or TKD, began as a contest and evolved into a sport that was eventually brought together under a unified rule set. While modern MMA was percolating and evolving for a long while prior to 2001, it wasn't until New Jersey drafted the unified rule set and Nevada used these rules to sanction an event that MMA was truly born. There was no "MMA" school prior to the sport of MMA.
Guys, you're welcome to your opinions. But you will never convince me that MMA is, at this point, other than a sport. Comparisons to BJJ or Boxing just don't work. Decades from now, when the training and techniques for MMA have become standardized, and people train exclusively for MMA events in "MMA" gyms, I might change my mind. But we're not there yet.
Yeah I don't disagree, but there has to be some bare bones somewhere, something to take away from from the sport front?
