Sparring - bad advice from sensei?

[sensei8]

Its been said in some ways but what you have here is the general issue with Karate these days.

The Sport vs Traditional debate.

In sport karate your goal is to score point and get more than the opponent. Therefore to leave doubt that you have scored can defeat your objective.

When we spar we are told a loud confident Kiai will normally be enough but that is the goal to leave no doubt.

In traditional karate i would agree waving arms and shouting is offensive. In fact from what i have heard in Japanese culture waving or arms and voice raising is generally considered aggressive and rude.

It sounds like your guest Sensei is very much a sport karate competitor who forgoes the tradition of the art. ...

Solid post!!
