My opinion of why there are so many TMA that are anti-grappling is becuase "we" as TMA have put in ALOT of time and training to learn something that has tradition, we learned all the things that go with it (the whole honor, respect, discipline, etc....). So many MMA fighters lack this. I know ALOT of MMA fighters that go out looking to prove themselves at a bar. They seem so quick to fight. I think alot of TMA think that MMA people are trying to take a short cut in learning only what they want to learn from 4 or 5 different arts. This isn't always the case though, not trying to put down MMA because it definitely is useful.
