I think some people forget that all Martial Arts aren't geared to teach streetfighting situations. A lot of discipline and mental toughness pertain to quite a bit of the teaching. Not to mention the rigorous training and dedication. I've watched black belt tests from some of these styles that cover days of hard physical and mental challenges.

If you want to learn to whoop someones ass on the streets or compete no holds barred, you'll probably want to crosstrain or join a MMA gym. If you want discipline, camaraderie, and a very fun hobby, try something like Aikido.
