And you think those two videos are representative of all self defense martial arts? How cute. And for the record in the second video they are in a contest therefor the were engaging in sport not self defense.Well that's the thing; In sport/competitive MAs we tend to test our techniques against living opponents.
That doesn't happen in many traditional MAs. So what happens is you get pretty forms;
But when the rubber meets the road......
As you said; If your opponent is made out of straw, all that kata stuff would work out just fine. When you attempt to apply it to someone trying to punch you in the face, things start falling apart.
