showing dangeous martial arts moves to friends

[Groinstrike]

I just realized that may have come off as insulting. It wasn't meant to be. Seriously, if you feel someone may try to fight you later, they are not someone you should teach. They are also probably not someone who you should be hanging out with. You mentioned being near black belt. being high rank makes you a representative of your art, and you should be careful of the type of person you train. They reflect upon you, your school, and your art. Even if you are young, that rank gives you a responsibility to hold up the reputation and integrity of your school. The rank is a symbol of your instructor's faith in you.

Locally, a man was shot in self defense. It reflects very poorly on the instructor who chose to teach him, and the martial arts community as a whole, as he regularly committed assault and battery and was ultimately killed in doing so.

It should also be noted that the man that was killed was an mma "fighter" as well as a violent criminal.

Back to the topic at hand, be careful who you teach. If they are a friend, show them basic stuff that will either make them bored and if they begin to practice the boring stuff it is probably worth teaching them.

Are school has refused to teach multiple people based on the fact that they may reflect poorly on our school.
