Dee, Don’t bring yourself down to his level, you don’t have to put him in his place, he’s already there. He is a person whose own self-esteem is that low that he feels the need to belittle others to feel good about himself. In my opinion you have done the right thing by showing kindness to this person, you have set a high moral standard. He will learn in time that there is a difference between learning a martial art and having a black belt, to that of being a martial artist. Respectfully,
