The purpose and methodology preserved in our To-Shin Do kata were not created to address mutually consented fighting, where we agree to fight another martial artist until one of us quits. Our practice methods address handling non-consensual violence. That means self-protection, or stoping harm when attacked with criminal violence. The purpose determines the strategies used to achieve the goal. The strategies dictate the tactics. The tactics determine the choice of techniques. “Winning a fight I agreed to take part in” is not the same as “eliminating harm from invasive criminal violence”. You can’t take the strategies, tactics, and techniques used to achieve one goal and put them into action to achieve a different goal. This is not a value judgement
