See, CN, again the problem is the basic assumption in the OP that you `get into [such and such a stance] and then you fight from it.' As in the discussion I cited earlier from Abernethy, you don't `assume a cat stance'. Instead, you maintain your hold on the downed attacker's arm, slip your foot against their back, raise your knee and drop your weight back and down—instant short cat stance, in other words—and keeeerackkkk!!, that's it for their elbow, should you decide to push things that far. Take a photo of the fight at the moment when your heel comes up and your body weight comes down hard on the attacker's hyperextended arm, and it's the classic cat stance. Take a photo of the moment you move forward to drive your forearm into the attacker's pinned arm above the elbow to hyperextend it with your full weight behind it, and it's the classic left front stance.
I think you have to take into account the way people have been taught stances, as well as other techs, since the karate-based arts went mass-scale the better part of a century ago. Most of us drill stances, blocks, punches etc. isolation, relentlessly. It's so much the norm that most folk cannot conceive of the fact that doing it that way was actually a novelty, going along with large class sizes, deliberately diluted technical content, and all the rest of what we've learned about the history of karate in very recent decades, eh? For a lot of people, stances are things unto themselves because that's how they've learned them, and the way you first learn something fixes your way of thinking about it pretty solidly, unless you can distance yourself from your own assumptions and rethink a familiar phenomenon in a way that makes it very unfamiliar and novel. How many people can do that sort of thing easily?
The best thing to do is simply put the alternative perspective and the counterevidence and so on out there and hope that it helps someone `improve their ideas', as the Brits say. If it doesn't... well, you tried, eh? :wink1:
