While I don't agree with the confrontational way drop bear phrased this post, I do understand where he's coming from. I'll put it in the context of the thread it spun off of and hopefully be less confrontational about it:
Kong Soo Do claimed that sparring is a suboptimal training tool for self-defense because it does not include a host of real world considerations: de-escalation, escape & evasion, environmental factors, improvised weapons, etc, etc, etc.
Kong Soo Do claimed that kata is an effective training tool for self-defense.
Drop bear notes that kata does not include any of those real world considerations (de-escalation, escape & evasion, environmental factors, improvised weapons, etc, etc, etc.) that Kong dinged sparring for not having. Drop bear notes a certain inconsistency - how can you say training method A is not good because it lacks certain qualities but say training method B is good despite lacking those same qualities?
Drop bear may be (as several people in this thread have commented) completely ignorant of kata and its uses, but he doesn't have to know much about kata to question the inconsistency of the claims.
To take it out of the realm of martial arts - if I tell you that a Toyota Prius is a poor vehicle for getting around because it can't fly or go on water and in the next breath tell you that a bicycle is a great vehicle for getting around, you might be confused as to what I am thinking.
Now, I'm not any kind of kata expert, but I would guess the defenders of kata would say that kata does not need all those considerations (de-escalation, environmental factors, et al) to be useful for self-defense because it has a different purpose than scenario training and is just focused on conveying certain specific skills and knowledge. You can train kata to gain that knowledge and skillset, and then use scenario training to address other issues relevant to self-defense.
This, by the way, is the
exact same argument I used in that other thread to argue for the value of sparring in self-defense training (see my 12:03 pm post). Sparring doesn't necessarily have to include all those additional factors that you can find in scenario training because it is more narrowly focused on training certain specific skills and attributes in more depth. I think Kong ended up agreeing with me on that after I explained my point multiple times in different ways.
BTW - I think we can have more productive conversations here if we can break the habit of treating everybody who disagrees with us as willfully ignorant.
