I have cross trained in a few different things over the years, some pretty extensively. In this time i've run into a lot of people who had misperceptions about Karate. When they know I practice (even moreso that I teach) sometimes it becomes "lecture time" and they proceed to tell me what's wrong with Karate. I am just polite about them and nod my head and smile, usually feeling it is not worth my time 'defending' something which I am convinced is effefctive.
One pet peeve I've run into is people who complain about "force on force". Usually this is done in reference to Karate blocking, but it's never explained exactly what is meant. I have never personally encountered what I would consider "force on force" blocking, even in Karate which I feel is not optimal. Even hard or forceful defensive methods make use of one's body positioning to disadvantage the attacker, and tend to redirect force. This is true even when uke techniques aren't properly understood. That is, even in (for example) soto-uke learned in "3k" fashion, the actual motion you are practicing travels along a different line of force than the attack does. That of course does not mean it is being practiced realistically, but it still doesn't seem "force on force" to me.
Have you experienced any "force on force" methods? is this is a valid criticism of Karate in places, or just a cultural artifact?
