I think we're mostly in agreement here. You made the same point here: "The difference between being an effective self defense art and being a sport or traditional "art" that is good for fitness and self improvement and lacking in realistic self defense aptitude has almost nothing to do with what "style" you practice and everything to do with HOW you train."Of course you have to teach the psychomotor skills before you just start beating on people lol. And most of the actual techniques taught can be interchangeable with many many other styles out there. The difference is in the training methodology and the psychological aspects. If all it took to be able to effectively defend one's self was learning a few moves, you wouldn't have so many black belts in pretty much any discipline getting beat up in street fights. It's what sets Krav Maga and other reality based systems apart from many other styles.
If you take a person who practices a different style... For example Aikido since it is the original topic and run them through realistic full contact blitz attack scenarios over and over by people who are attacking them with a variety of very violent and unorthodox attacks, you will quickly find that Aikido practitioner being able to better defend themselves. The difference between being an effective self defense art and being a sport or traditional "art" that is good for fitness and self improvement and lacking in realistic self defense aptitude has almost nothing to do with what "style" you practice and everything to do with HOW you train.
In my personal experience... And I know there ARE exceptions, most traditional arts poorly prepare their students for violence because of how they train, not because any one system is inherently superior.
I will be writing some new posts about just this sort of thing on my blog if you ever want to read my babbling nonsense! It's something that I'm obviously passionate about since my ability to train others effectively can be the difference between their survival as well as providing the tools necessary to make an arrest with a minimum amount of force necessary. I'm currently working on what is going to probably end up being a few posts about the strengths...and many problems with training scars created when cops train in Brazilian jiu-jitsu alone. Like all arts, it's important to diversify
That's really my point. KM is effective (when taught well, of course) because of the training methods used. More and more, I'm starting to see many of those same methods show up in TMA dojos, as well. I think it's part of the positive influence KM has had.
