now thats a stupid thing to say, and comes
all you TKD people are just brainwashed thinking that what you can do in sparring in a nice loose uniform you can just as easily do in street clothes and shoes on cement.
TRY IT
then get back to me and let me know how funny it was when it didnt work and you fell on your butt.
At the age of 17 (que Star Wars "A Long Time Ago, in a Galaxy Far Far Away) I was mugged by a man with a knife. I did all the things you're supposed to do, including giving him my wallet and the rich sum of $6 it contained. The unfriendly man with the knife was convinced that I must have more money on me, and was willing to kill me to get it.
He slashed, sideways, at my throat. I performed a rising block. In hindsight not the best choice, since I didn't get back quite far enough, and as the knife rose it caught my left eye. That's why I wear a prosthetic today. I threw a roundhouse to his solar plexus, then a hook kick to his head. He landed on his hands and knees. I threw an axe kick to the back of his neck, which ended things. I then ran.
While the axe kick landed low enough to make you happy, the first two kicks were both 'above the nuts'. I did not fall on my butt. I did not have any difficulty caused by my clothing. I am not a professional fighter. There were two problems with the encounter, and neither of them had anything to do with the kicks.
1 - I screwed up the block on his knife hand.
2 - I had to hurt him even worse than he hurt me. Necessary, yes, but still regretable.
The other thing I learned from this is that we, as a culture, ought to reconsider training ourselves to be victims. The last few generations have been taught 'don't fight back, give the badguy what he wants and he will go away'. I believe this to be a mistake. Give the badguy what he wants just long enough to distract him. I ought to have dropped my wallet when I handed it to him, and when his eyes reflexively followed, attacked.
Teaching our children to be victims in this way is, I believe, why 9/11 was our own fault. Terrorists cannot highjack a plane with a box cutter if 15 people jump on each of them.
Every attack we train with is useful. Not all are useful in every situation. But none are useless either.
