In your opinion what is the most "McDojo"ed martial art?

I would have to say Taijiquan.

It's been so Mcdojo'ed most people believe it to be a health exercise.

In our dojang I see this all the time. I am actually the example you put forward. I attend class with my two sons. Youngest is 10 and the eldest is 13, I myself am 33. I'm the one who takes it seriously while my eldest just goes through the motions and my youngest sees it as fun. We all started at the same time four years ago. I am a red belt, my eldest is a blue belt and my youngest is a green tip. (He is in no hurry to grade because he can't test for his black until at least 14). My eldest hasn't progressed past blue because he isn't taking it seriously enough. That is the key right there. At some stage you have to take it seriously or you will get to a certain point and go no further. It isn't easy all the way through to black. Our gradings take training performance into account and my instructor has no qualms about refusing to grade you if he doesnt see the effort, or he is correcting the same thing over and over again. We have to take it serious at some stage and you aren't going to do something for years if you are just there to relieve boredom. Saying this though we do have a lot of fun in class with games that focus on balance and reflexes so it is not all serious martial arts. I don't think there is a better way to differentiate between the serious student and the hobbiest because eventually the training itself eliminates the students who aren't taking it as serious as they should. Time always tells.

As a Taekwondo Master, I would have to agree with most of the folks here, but for different reasons. The main reason TKD has become watered down is because of something called the "Miracle Plane." Gentlemen would board a plane in Seoul as a 1st or 2nd Dan (at most, some had less training) and land in Detroit as a 6th or 7th Dan. Upon discovery of this, Korea denounced these men and removed their credentials, only to embolden them to promote their own Associations and styles of Taekwondo. With no authentic backing from the homeland, these schools became businesses first, and sought ways to increase enrollment and income. What you have now is people so far removed from the real art of TKD that what they teach does not resemble it at all.

There is nothing wrong with promoting the sport aspect of Taekwondo, so long as those practicing the sport are also being taught the art and science in a traditional manner.

In all honesty I would say Tae Kwon Do. I've sparred people who trained in Korea and let me tell you, they are the real deal. I don't think I've ever been kicked in the head so many times.

But here in the US, TKD's been watered down to a point where there's almost nothing left to respect about it.

The TKD McDojo's cater to people of all ages and physical ability. They typically target kids. I understand the importance of building up a child's confidence, but letting them flail their legs around in what are the ugliest kicks I've ever seen, telling them they're doing good enough and then handing them a black belt (after only 1 1/2-2 years) is disgusting.

They say they'll teach self defense but they never touch on self defense at all. All they do is take your money (or your parent's money in many cases) and then have you slap some pads with your feet and break 1/2" plywood boards.

If you train under a good instructor you can really develop flexibility, footwork and good technique, but more often than not they just want your money.

It's a shame though, because a lot of those instructors earned their black belts in Korea, so they know what they're talking about, they just put making a profit before teaching real TKD.

I would say

1 - Tae Kwon Do

2 - Karate

3 - Kung Fu

and with the rise and popularity of the UFC and MMA comps BJJ and Mix Martial Arts too.

TKD. They are known for promoting children as well as adults to higher ranks when their skills are so lacking just to fill their schools with black belts. This in turn creates the persona that it is a good school when you see twenty-five black belts on the floor to an uneducated person looking for a martial art school to join. On top of that they encourage some of these black belts to then go out and start schools of their own just to spread TKD which further waters down their art even more. The standards that they apply in this country are not the same as those that are applied in Korea where it originated and is their national sport. This is all done for the sake of spreading TKD and for greed. Ask a school owner what he has to pay per year for his school to belong to and recognized by the World Tae Kwon Do Federation. Not only that but students as well incur some costs through testing fees, diploma fees, costs for membership cards, etc. If you do the math and have 200,000 people who practice TKD in this country paying you $5.00 a piece just for a membership card its a million dollars. They literally have built their art into a money making vehicle in this country that cares little about the quality and standards that it once stood for and laugh all the way to the bank. I personally know a family of brothers that are Korean instructors that helped bring and establish TKD in this country in the 1960s. Privately they have very little good to say about it and the path that it has been going down since the 1980s for the sake of money.

We all know the answer to this

as all martial arts have thier own branches of Mcdojo's its the ATA schools that have it hands down. I really am not putting down all the ATA schools or the students/instructors you allways have the good with the bad, but ATA is making a reputation for itself by putting kids through rank so fast it would make your head spin and black belts on kids younger than 16 should be unheard of, But they look at it like its a buisiness

Tae Kwan Do.

Once it became a sport it stopped being a martial art and became "tag".

This studied the art long before this occurred.

Immediately after the television series starring David Carradine, "Kung Fu" was broadcast, most kenpo/kempo schools painted "karate/kung fu" on their windows suddenly and mysteriously teaching both...

Virtually any one of the former "arts" that has degenerated into a "sport" qualify to be McDojo.

What martial art are you thinking of that fits the description?

I suspect you already have an answer. If so, then to you it is what it is. In any art there are some who teach and some who pretend to teach. It's bad to generalize and condemn an art as losing its soul if there's some black sheep in the herd.

TKD would be my first pick, but quickly rising up in the ranks is BJJ.
