Some people are interested in things besides training for fighting.
The article made a good point in that alot of people send their kids to local karate classes or suburban boxing gyms and don't give the slightest thought to whether or not they can actually fight - its just babysitting or maybe excercise. Likewise, we have the "workout of the week granny" and the "overweight desk jockey" who really aren't all that interested in actually fighting people or developing skills for doing so, and just want to burn some calories in a more exciting way than running on a treadmill. Lastly, we have the "cultural warriors" who can be compared to civil war reenactors, who like the idea of being part of a long heritage and aren't necessarily interested in fighting the best they can.
Then there are the people who just don't know any better and think that chi blasts are the soul of sucessful self defense.
And let's not forget that there are those people who realize there is a large difference between MMA fighting (or fighting of any form) and self-defense. Those people will learn self-defense systems and not MMA fighting.
