Look. My name is Jason Scott. I've been training since I was four. I don't ever train anyone unless they want to know for defense. I teach my students to always use other means first before you use your skills.
You sound very judgmental right now. I just need an instructor two nights a week. I also compete in competitions, and you are required to have a belt color. I know more than just karate. If you aren't interested, it's fine. I'll find someone else.
