MMA does not help MA. The silly attitudes and egos are like watching a bunch of 1st graders. Also, MMA does NOT show what "actually" works.
As others have pointed out, these are hardly confined to MMA. I've seen relatively little of it in professional MMA. And TMA can hardly point fingers. See Boztepe vs. Cheung, ITF vs. WTF, TSD vs. Karate, CHKD vs THKD, pretty much any two Silat lineages
ad nauseam, ad infinitum. At least in the competitive sport the ego and talking yourself up can be a legitimate part of the mental game - psyching yourself up and the other guy out. It can serve a purpose. In the TMA it's generally a lot less connected to any real-world goal.
In MMA there are no.....
Eye gouges, no knife hands to the throat, no downward elbows the head, no strikes and/or elbows to the back of the head and spine, no small joint manipulation, no kicking/or kneeing a downed opponent in the face, no pressure point attacks.
These techniques work in the Real Life. These techniques worked, the few times I had to use them in Iraq while house clearing.
Frankly, most TMA are lousy at that sort of thing. The ones that spar don't use these techniques in their bouts. And what they teach is often pretty lame, stuffed into a dance-form kata or taught as unconnected technique. Is it really what their practitioners revert to under pressure? Are these things so off an MMA player's radar that he or she couldn't bite, elbow or stomp a downed enemy?
I'm honestly guessing no on both counts.
Let's take a look at what they have in common - boxing and wrestling loosely defined. Maybe MMA fighters are specialists in this. Are their boxing and wrestling skills as good as or better than most TMA types'? Definitely no worse. Are they in better condition? Almost certainly. Wrestling and Thai boxing require a hellish degree of fitness.
Traditional Martial Arts teach respect and dignity, along with their techniques.
Says so right there on the label. In about thirty years of this game I can't say I've seen them do a very good job of it. "Respect" tends to mean a lot of bobbing up and down combined with worshipful butt-kissing to anyone with a fancier colored strip of cloth and a highly developed, rigidly enforced status system.
My working definition of "respect" and "dignity" are a little more nuanced than that.
If we're talking about fighters or even people terrified to the point where they turn into vicious scared monkeys you respect the fact that one lucky or desperate attack could ruin your day. So a prudent person has manners which keep him from putting himself in danger. Someone who has put in a lot of time and effort deserves recognition for it. And good manners are just plain good manners anywhere. Besides, if you don't have them people tend to stay away from you.
Dignity? If you mean physical and emotional confidence I suppose MA can be good for that. So can MMA. So can anything which gives you a sense of real accomplishment.
MMA is a crude sport. Nothing more. It is IMO- a sport we can do without.
A sport? Certainly. People who compete make no bones about that.
Crude? Hardly. It has developed very quickly and to a very high level so that the early winners like Royce Gracie aren't even contenders anymore. It's highly optimized for what it does. That isn't everything, but it covers a whole lot of territory. More than most TMA, to be quite honest.
Something we can do without? Yeah, I guess so. We can do without all sorts of things. But it does provide a valuable service. All sorts of people were fooling themselves and had no way of seeing if what they were saying was true.
"My striking can stop any wrestler". No. Not really.
"My martial art is unstoppable". Didn't turn out that way.
"Our anti-fill-in-the-blank techniques are invincible". Proved false.
"I don't have to learn anything about what anyone else does. All I have to do is practice what they teach us." Not if you want to put up a good fight.
And so on.
