I have made many statements on kata. I dont belive you have read all of them, but to detail my view in greater detail and more accurately: The fighting value of kata is dubious at best and it factually has no fighting value on its own. The spirtual/fitness value can be argued on a case by case basis, but the former is down to the beholder. If you are not a spirtual person it would be useless. You can safely erase it and not loose any fighting effectiveness. (as has been proven by combat sports and martial arts that dont have kata in it)
I agree with your statement within the context of you, personally.
You have never learned kata. You do not understand it. Therefor for you, the practice of kata is worthless. I do agree with that.
Kata is not necessary as part of learning to fight. there are, obviously, many clear examples of folks who can fight, have learned to fight, have studied martial methods that do not include kata and yet can fight very well. There is no room to argue that.
kata that is poorly understood can also be a waste of time and effort. So for some other folks who practice kata, I would agree that it is useless and is a waste of time, as well.
some kata are, in my opinion, poorly designed. They are created by folks with a shallow understanding of their martial methods and the role that kata should play within the context of training. These people create their own kata, and for many of them, their creations are garbage. For these people and their students, the practice of kata is also worthless.
You do however, fail to understand that kata can be a valuable training tool, one of many training tools, one tool in the toolbox, for those who understand it. For them, it is a useful tool. The fact that kata is useless for you, in no way negates the fact that it is very useful for many other folks.
You can cut a log using a variety of tools. An axe does a good job, as long as you don't need a clean and straight edge. A hand saw can do a good job, can even give a good clean edge if you are skilled with it. A table saw does a good job too, as long as the depth of cut is large enough to handle the log. Even a knife can get the job done if you work at it long enough, and if the knife is big enough.
If you only know how to use a hand saw or an axe, that does not negate the fact that others can get the job done using the other tools I mentioned. If you don't understand how to use the tool, that is your shortcoming and your lack of education, and not anybody else's problem.
Now I have educated you on kata. From here on, you know better and you have no excuse to make statements based on ignorance, because you are no longer ignorant. If you do continue to make such statements, then you are a liar. I suggest you simply do not discuss kata at all. It is way way over your head.
