Mostly Harmless
I’m genuinely trying to track this thing. Are you saying doing kata will make a competent fighter incompetent? It seems not. I take your argument to be that overemphasis on kata can lead to neglecting things that actually build skill. So, it’s not the doing of kata that’s leading to incompetence. It’s the doing kata to the exclusion of doing other things, like fitness, sparring, and fighting. Do I have it right?You were asking how kata can detract from fighting ability. Overemphasizing it is one way it can do that.
If we agree that focusing too much on kata detracts from fighting skill, and Martial Arts that don't practice kata at all suffer no adverse effects, that pretty much shows that kata practice has a potential negative impact on fighting ability.
True, but how that artist is trained matters as well. If you train in bullshido for decades you'll never be as good as you could have been if you spent that time training in something legit.
