Then don't train with them. Move on and find someone with good taijutsu reguardless of their rank and train with them. I don't give a rats backside what rank somebody is either, a 9th Kyu or a 15th Dan can show me something and I can find something to learn from them. I don't ask rank, I look at their movement and attitude. It is not my place to either give rank or question rank, it is my place to find the best training I can. I would not be so bold as to infer Hatsumi Sensei had made a mistake in awarding rank to someone. Example: I have been an Electrician for way, way too long (25 years this year) and that would be like somebody who just strapped on a tool belt questioning the way I have a large commercial job timeline laid out. They may have some degree of knowledge, maybe even went to college for the trade; BUT, while they were reading books and buying beer, I was laying out the electrical for multi-million dollar jobs. I'll be polite and listen to their argument, then tell them to go pound sand someplace. Are we going to call THE BOSS to task because in our little narrow view of the art we don't agree with his actions? Not me!
