When people come into my dojo (well the dojo I rent... it's mine while I'm there) they follow the rules I have or they leave. It is very simple. If someone doesn't like the rules I have, go somewhere else. I don't care why you won't follow the rules I have. That is between you and whoever. My rules are between you and me. No one is forcing anyone to train with me. I don't charge anything when I teach, hell, it costs me money to rent the space. If you don't like it you can get your money back
Just like many people here I don't want Keith killing a baby seal in my living room. If God tells him to do it, God needs to send carpet cleaners, too.
