MZ1, I've had full contact fights in the past under MMA type rules, and I've had street fights. They are different. Yes, the training MMA fighters go through is more helpful than those "tma" schools who never test thier stuff under really resisting opponents. However, training under a ruleset does have its disadvantages in a SD situation. If you don't understand why this is so, it is an indicatiion of some miopic vision. Also the goals and enviroments are completly different between the two. What you must be aware of is different. Those differences can lead to some pretty awful problems in self defense.
You will fight how you train. No exceptions, MMA or TMA.
Your personal experience doesn't make you the final authority on how every streetfight must be like.
There are many factors involved, with the most obvious being, most streetfights are not to the death and crap like many SD people pretend they usually are (to sign up students or keep them from going to MMA). Every phone's got a camera nowadays. There are tons of streetfight videos on the internet now. Not just Youtube, but the X & R rated sites where much more brutal fights are posted.
In such videos, about one out of a hundred has someone beaten severely. Most of the time...once someone is KO'ed or knockdown, the fight is broken up before anyone comes close to dying. Either broken up by bystanders, police, friends of the loser or even friends of the winner....like a Referee. Many times the winner just stops on his own. I may have seen ONE or TWO out of thousands of fight and violent attack videos where someone actually does die.
You say you've had streetfights. Me too. Now what? Your MMA type rules fights...they can mean anything from smoker fights to low level, local tournaments. I beat some of the MMA fighters in my gym who've had more fights than me, they know what's up. If you were a Pro, even low level Pro in MMA, I may listen more to your argument.
My friend, who's pure TKD, HKD, Boxing and hates MMA...has had over 50 streetfights and a small room used to display all of his TKD tournament trophies & medals. He used to take PCP just so he can train longer and harder, and then go out with his friends looking for fights in Black neighborhoods where his stores were (he's Korean). Most of his fights were him punching some loudmouth guy in the face for stepping up to him at his store, the guy drops or is KO'ed, then it's over. He's fought 5 Chinese guys at once before. He's been in firefights in the streets and at his stores. He's been shot, those fighting friends of his...some were shot to death, etc. He used to have a deathwish when he was young. But his vast street fighting experience means nothing in terms of setting some kind of mold for how all streetfights must be different than in the cage/ring as you imply.
You will fight how you train. No exceptions, MMA or TMA.
No exceptions huh? So seeing that how SD and TMA people spar their ninja techniques by pretending to eye gouge someone or pretending to kick them in the nuts....this must mean that when fighting in the streets, they're going to pretend strike just like how they train?
Here's a good example of a Karateka who spent probably most of his time never actually sparring hard for KO's, so he ends up just fake fighting as his normalcy......and gets his bell rung by a Boxer who trains for real by taking real punches to the head and dishing the same out.
