NO style should critisize any other style. All styles bring something to the table. As a Martial Arts Community, we should share our knowledge with eachother. My Sensei is a Sixth Degree in Isshinryu yet continually goes to other schools, tournaments and and seminars which include all different styles and tries to take the best concepts from each one. He always says that we, as students, should take the blinders off and recognize that how much we can learn from one another.
