MMA is a crude sport. Nothing more. It is IMO- a sport we can do without.
It is a highly technical and strategic sport.
And don't give me that crap about participants being disrespectful, it's simply not true. At the top level it becomes entertainment as well, and that's all you are seeing. No MMA gym would tolerate that sort of attitude in training as it would lead to constant injuries.
Put TMA in the entertainment realm and the same thing happens. In movies 99% of people that do martial arts are bad guys, of course the good guy always whoops all of them, but I'm not sure the higher percentage of 'bad guys' shows that traditional styles are 'better' in entertainment.
I can also say that I have seen a lot more disrespectful behaviour in 'traditional' events then grappling / mma events. But that is just personal experience.
