OK to the OP-- this guy is talking out of his ass about Krav Maga.
Those Krava Maga techniques you are pooping on are actually successfully employed in life and death situations. I know people personally who have successfully used Krav knife and gun disarms as well as in hand to hand encounters.
Note that we are not talking about martial arts, we are not talking about sport fighting, we are are talking about practical self-defense on the street. BJJ is great and Muay Thai is great but how about when it's 3 people on one. What if someone pulls a knife on you and you run, but they run faster than you? What if you have a gun to you obey and you give them your wallet but then they shoot you anyways? Krav Maga has technical solutions for those situations and moreso, a GOOD Krav school will help you develop the mentality to SURVIVE LIFE OR DEATH SITUATIONS. A huge part of Krav training is the mental conditioning and the ability to stay strong and keep fighting under extreme stress and duress. They don't show that in the technique manuals. No technique will provide instant assured victory for a 100 lb woman vs a 300 lb trained/street experienced thug BUT continuous relentless resistance and attacks will and do dissaude attackers by making thier tasks difficult and unpleasant.
The reality is that if you have a trained or experienced crimminal dancing and feinting in front of you with a knife, you might be in some very serious deep shit. Or, if you have someone pointing a gun to you and keeping their distance instead of walking up to you and waving it in your face (watch youtube crime videos to see that behaviour pattern), you may just be ****ed. A good Krav school will help a bit against those scenarios as well though and teach you situational awareness.
Regarding the technicals of Krav Weapon defense, a good school will show you how the defenses are not stiff, how the basic essential defense training also works against knifes, sticks/bats. A good school will train you with multiple angles, unpredictable attacks etc.
Regarding chick tricks, I'd like to see you guarding your nuts and eyes while throwing a powerful punches. Very few crimminals will not be trained martial artists/fighters and many street "fights" will not be one on one. Krav helps with all of that.
Last thing- I said "good krav school" a few times. Yes, not all krav schools are good and neither are all bjj or MT schools.
To the OP-- what city are you located in? I could possibly reccommend a good krav school to check out.
We all "know people" that have supposedly successfully used techniques from any bullshido MA out there including garbage like Tai Chi and Aikido, which are better categorized as new age spiritual practices rather than fighting techniques. While I respect that these arts are good for relaxation, spiritual and recreational purposes, they will get your ass kicked if you think they'll work in fighting.
Anyway, were you there when said attacks occured on Krav Maga guy? No? Oh the guy just told you, mmmhm, I see. And of course he has no vested interest in defending an art that he spent years and tons of money training, gives him a huge self-esteem boost and makes him feel like some kind of badass. None at all. Hint: people lie, or at least exagerrate ... only believe your eyes. I see proof of Muay Thai in MMA, which is the closest to real legalized form of fighting. I've also personally seen (and not just heard) MT/Boxing type proved on multiple occasions in street fights. Not to mention, there's tons of videos on YouTube and such of Boxers and MT guys taking out multiple dudes in a street attack, ones that don't look blatantly faked. Here's one such of a boxer:
I know MT and boxing are different, but they're related and MT has absorbed most of western boxing and is proven and tested under the same circumstances i.e. in the ring. And there's videos for MT in street fights out there too. Any and all such "proof" for Krav Maga and Bullshido type MAs are blatantly and obviously scripted. That, or they're slow ass "demonstrations" with fully cooperating "attackers" that allow themselves to be grabbed, leave themselves open and unmoving for 10 secs while some chick releases her slow ass combo on his junk and eyes. Real fights are far more fluid than the crap shown in those demonstrations, the attacker usually reacts.. fancy that. I'm not completely making an opinion based on nothing, my brother took the thing for years, and I've seen it's techniques up close a lot but there's never any proof, only hardcore feelgood propaganda to stroke people's egos.
As for the "there's bad schools out there, but the art is good" excuse, that is the first cop out for every bullshido art out there. But EVERY krav school on the internet shows these same fake ass demonstrations of techniques that anyone with an intution and experience of real fights will know that they will never work against a resisting opponent swinging or slashing at you. Funny how you never hear excuses like that about Muay Thai, Boxing or MMA schools ... because the techniques WORK. No matter where you learn it, MT, Boxing and MMA will inevitably teach you to destroy, because it's earned from hard work and pain in REAL, fluid fighting, with minimal rules. Not comfortable feelgood stuff that serves as ego-boosters without putting in real fighting.
As for your deadly krav techniques working against multiple people, if they won't work on one, they certainly won't work on multiple. Even more people reacting to your slow scripted choreography.
If you can't get away by running, use your common sense and proven fighting techniques. Yes, go for the groin, eyes and throat if you can, but you don't need 10 years of training for that common sense shit, I look for those openings even just knowing MMA. But knowing how to throw powerful boxing punches, MT knees, elbows and kicks will create openings where there are none. You'll power your way through by hurting the other guy whether even if he doesn't let you or leave you blatant openings.
I am very familiar with the so called "hardcore" mentality taught in Krav schools. IMO more than helping people survive, it makes them act like tough guys and aggressive, which will probably get them in more trouble than saving them. Because while in MT, MMA and real fighting arts, there is a constant developing respect for the realism of fights, other's abilities and humility from getting your ass kicked in order to get better, there is no such thing in the fake scripted world of Krav. And they're constantly analyzing every little thing as a threat, overreacting to the craziest things like someone walking close behind them in a hallway. Because you are somehow this badass dude/chick with a chip off his shoulder that is "trained to kill" against any ridiculous odds and is always looking for threats. More like it will get you killed. Again, no one will hold still like that in real life while you make a grab for their knife or gun, or convieniently pop their heads into position for a knee after your first attack in a scripted combination. They could just as easliy react with a wild stab. But no.. they never teach any form of fluid defence or reaction in Krav, because the enemy will always react exactly the way you conveniently script them, and fall like flies at your deadly blows.
