I've tried a bunch of martial arts and seen a lot more. Don't think I've ever encountered one where 90% of the art would be illegal in all forms of sparring or competition. I've personally sparred with weapons, groin strikes, knees, and hair pulling as well as the usual throws, chokes, joint locks, and punching/kicking to 95% of the body. I've watched competitions where elbows and head butts and stomps to the head of a downed opponent were legal. Maybe there's an art out there I haven't found which is 90% eye gouges and biting?
Kind of a dangerous assumption there unless you have the experience to know that you can reliably hit a non-cooperating opponent in the temple and daze him. Other than getting in a bunch of real fights, your best bet to get that kind of experience would be training in an art which includes full contact sparring.
The problem is that any kind of training for truly damaging techniques has to have some sort of flaw or else you are just actually injuring your training partners.
Let's say you practice an art which relies heavily on attacks to the throat, groin, and eyes. Do you drill your techniques by actually punching them full power in their unprotected throat, actually kicking them full power in their unprotected groin, actually gouging their eyes out? Probably not.
You have to modify things somehow. Perhaps you pull your blows. Perhaps you aim slightly off target. Perhaps you equip your partner with protective gear.
All of these possibilities run into potential problems in a real fight. If you've been pulling your strikes short of real contact, are you going to be able to turn on the "full contact" switch in a fight? If you've been aiming off target, are you going to be able to turn on the "accurate targeting" switch? If you've been equipping your partner with heavy duty protective gear, do you know how an opponent will actually react without it?
All of this isn't even addressing the issue of defense. If you can't stop an opponent from hitting you in the face or recover from being hit, you'll probably never get to unleash your devastating groin kick/ throat punch/eye gouge combo.
My personal opinion is that if you can develop the skills to strike with power and accuracy to the 90% of the potential targets on a resisting opponent while preventing them from doing the same to you, then it is relatively simple to add a few supplemental drills to remind you of targeting the remaining 10%. If you can develop the grappling skills to control an opponent who is trying to do the same to you, then it is pretty easy to learn the opportunities for "dirty fighting" moves like biting or eye gouging.
On the other hand, if you can't do those things, then your odds of effectively kicking someone in the groin or punching them in the throat go way, way down. You need a delivery mechanism.
Just going off Kenpo for example (and there's some very bad Kenpo out there I'll admit it), if a centerline is open I think literally every primary target of choice for self defense is illegal in UFC. It's not just eye gouging and biting right? Throat strikes. Breaks. Kneeing or head kicking a "grounded" opponent. Groin... Etc
Anyway. There's Fighting. All kinds of things are fighting. School fights, bar fights, slappy fights, UFC fights, Boxing matches, hockey fights...
A self defense survival fight? That's something you can spend your entire lifetime training for and never need it.
I guess my argument (and I prefer discussion to debate) would be something like.
I think this technique is effective .
TMA trashing fanboy: I want to see it at full speed with full contact and power or I won't believe it works.
Me: are you volunteering to be the "bad guy" for the demo?
You'll get no argument from me about the merits of sparring. But I view sparring as very non style specific, there's only so many ways to punch and kick. When I spar it's basically kick boxing. But for conditioning, mindset, and learning distance and striking... I like it. I wish more people did it.
Of course you risk brain injury and concussion. I think that's why a lot of schools have moved away from it. It's liability.
The Kenpo school I went to back in Texas back in the day, we full contact sparred every week.
One problem I have with grappling is this...
I prefer to keep distance. If I go to the ground someone took me there. I'm going to try like heck to get back up. I know my strengths.
And someone smaller, in my opinion should never surrender distance and willingly engage in grappling. It's very hard to run away.
The third thing is in grappling, and I'm not the only one to ever point this out...but like even in my personal experience when I was being choked out. I had a friend there watching. He yelled and yelled at the dude to let me go. It would have been very easy for him to kick my attacker in the head or bash him with a rock. But no... Pacifist friend lol
There's always a crowd around .You grapple you lose all focus of your surroundings, what's behind you and other threats. Your opponents buddy is very likely to come up behind you and knock you out, especially if you're winning. If you find out your opponent is more skilled than you it's very hard to retreat.
Look it has it's place. But no art is perfect. But I argued it before and I'll mention it again.
The loser of a UFC fight. Were his techniques effective?
Some people say Karate is a joke. Kenpo is ineffective. Kung Fu is a worthless fake waste of time. Only UFC MMA BJJ or Muay Thai is worthwhile.
But really...
It's always assuming "all things being equal".
Reality is, all things are never equal. The outcome of any fight is determined by such a crazy set of veriables unique to each fight. I'm not sure "Fighting Style” is the top of the list.
Size, Fighting Spirit (and the mental ability to actually harm another human), Strength and conditioning, striking skill, intelligence, instinct and experience. It all matters. Add in dumb luck and the opponent and the setting. ... It's a lottery.
Personally I choose to carry where I'm allowed to. Someone comes at me all crazy MMA style bigger than me if I have time I'm pulling my weapon.
I have no idea what my point was .
