I respect your opinion, but I still don't believe you (anyone) should judge the entire art, as it is taught today, by generalizing based on some bad schools. I completely agree that there are too many sell out schools that "teach" only for the money. However, there are still good schools and good instructors just like there are good kung fu schools and instructors.
You might not be overly impressed by what TKD you have seen, but I assure you there are enough TKD masters and their students who I believe would surprise you. You say that the training your sensei saw is probably extinct and that one would be lucky to find someone who understands the original intent of TKD. This is what I meant when I said you can't judge an entire art when you don't really know enough about it. There are good instructors and there are definitely good TKD schools. Finally you say that TKD is just sportified. This is one statement I know is not true (not completely anyway). Read my first post in this topic, but here I will talk more about it. There is Olympic style tae kwon do, which is very sportified. An example would be the typical WTF school. That is fine if you like sports, but don't assume that is the extent of all the TKD schools. Many many TKD schools are not sportified. Take mine for example. When we spar, we do not keep a score or see who wins. We just spar and learn from our instructors how to use TKD in sparring for the same reason one would spar in any martial art. There are many schools like this, and that I know is a fact due to my own experiences.
