You seem to be totally missing the point.
What's next, he finds some kids brawling in a backyard somewhere and reports on the horribleness of mma?
His point is not that poor, shady promotions and crappy fights are what MMA is. It's about how MMA is perceived.
I comment all the time on backyard brawls bringing problems to the sport of mixed martial arts. That doesn't mean I this MMA is tantamount to a backyard brawl between pubescent boys.
Curtis' point is that there needs to be some resposibility exercised by promoters to put on good MMA, because good MMA is what helps the sport grow, while bad MMA inhibits growth.
Keep in mind this guy is a die-hard MMA fan. It's not an issue of making a judgment call about the nature of the sport because he thought a promoter was a douchebag. It's about a concern that other people might make that call, and that politicians and other figures might attempt to exploit that judgment.
