A couple of very good points that i totally agree with. I prefer to train to be an all around martial artist. Not just a "one trick pony" as they say. I think to focus only on striking or only on grappling is a big mistake. Unfortunately some people get so caught up in their one and only style that they don't bother training to be an all-around fighter. Some arts are more comprehensive IMO and cover the bases a little better than others. But all arts offer something good and no style should be taken too lightly.
There definitely are some TKD schools out there where the training is not up to par, but that is also true for any style. It depends alot on the instructors and how they teach and how qualified they are. TKD is pretty much taught as a sport these days as is Judo and many others.
My primary focus in training is to be able to defend my self and people I care about. The excercise is merely a bonus and I don't do it to meet people and socialize. Nothing wrong with that but that seems to be the biggest goal for some.
I find it really annoying when martial artists say they have no respect for this art or that art. That's just being close-minded IMO and ignorant. My preferred art is Hapkido because I feel it prepares a person very well for self defense situations. But I also enjoy learning things from many other arts that Hapkido may not offer. I don't beleive there is one perfect art out there. What I look for are techniques and concepts that I think are realistic and will work in a so-called real fight. Some of the stuff I like are: Russian Sambo, Modern Defendo, aiki jujitsu, Machado Brazillian Jujitsu, CDT(using non-lethal force to subdue) and so on.
Also annoying are people who say stuff like "that kunf fu stuff is crap, or "martial arts don't work in REAL fight". But I think Rocky covered that pretty well already. Anyways I'll stop rambling now.
