Sounds like somebody has an axe to grind with karate.
It's hard to start pointing out what is wrong with this analysis of the sport, since he demonstrates a very poor understanding of traditional karate practice. I make no excuses for black belt mills created by split-off schools of karate that don't practice full contact sparring, but from somebody who trains in traditional Okinawan karate and has done for several years, here are some pointers:
1. Stance - the wide stances used in karate kata are not intended for use as fighting stances. Many of these stances were adapted from yoga and are used to condition the muscles in the legs, building a stronger lower body, improving balance and economy of movement and building core strength. During kumite karate practitioners only occasionally adopt wide leg stances, for the rest the emphasis is on speed of movement in and out of range of the opponents body. Sorry pal, if you don't know this then you're not qualified to talk about karate.
2. Kata - kata is where stances are primarily employed. The point of kata is to increase efficiency of movement, balance and strength. Kata is also used to refine technique, ensuring that blocks, kicks and punches do not unbalance the practitioner or result in injury. Most dojos emphasise that students need to be *relaxed* to punch and block with maximum effectiveness, and the most frequent correction I see during kata is for tense, rigid posture. An effective kata practitioner will demonstrate fluid, liquid movements during kata, building a lightning fast, focused technique that is extremely effective in ending fights with a single blow.
3. One strike kill - A karate punch performed at full force by a skilled practitioner is easily capable of killing an individual. Kyokushin practitioners can punch through layers of tiles, bricks and ice and are perfectly capable of crushing the human skull - the main reason head punches are not allowed during sparring in this sport. Strikers to the upper neck can also be lethal. One of the reasons why karate does not always fare well in bouts between different styles is that a number of its strikes are lethal - for instance when being rushed by a brazilian jujitsu black belt, a strike to the neck would most likely end the fight, and the bjj student's life. Furthermore, in traditional karate students would often grow their toenails, allowing them to sever arteries with kicks.
4. Karate does not apply to real world situations - karate can be used to defend against knife and blunt object attacks. Knives and blunt objects have not changed in nature during the last hundred years. A quality dojo will ensure that students are prepared to deal with blocking weapon attacks.
5. Karate takes too long to learn and you still can't fight - full contact dojos encourage sparring from day one, and students are forced to take on higher graded students. I can't think of better way to learn how to fight. An experienced practitioner will do better in a fight - as is the case with any martial art.
Full contact schools also do body conditioning that prepares students to take a punch. The abs, chest, forearms, upper arms, outer leg, inner thighs, instep, shoulders are just some areas that are conditioned so that pain is not a factor during a fight.
Developing and manifesting the incredible elegance of this sport can indeed take a lifetimes study, and this is what makes it a martial
art. The viper speed, economy of movement and elegance shown by the experienced practitioner is virtually unparalleled in martial arts. (

The key to learning karate as both an art and a viable self defence technique is finding a quality dojo rather than a black belt mill. Look out for kyokushin, full contact shotokan and goju kai dojos if you wish to have a taste of traditional karate.
