Does it though, when in other classes their instruction is spot on? no touch KO's are a belief thing as is religion, are Xtian instructors techniques impinged because they sit and pray before the class for the techniques to work and they credit their wins to G-d being on their side when they fight in competitions?
if no touch KO's are taught in a self defence class how is a BJJ class where they just teach BJJ suffer, how does it impact on their other classes when this thing is only taught in one? As I've said many instructors teach BJJ, TKD, MT, Judo etc perfectly well but their Sd classes are utter rubbish especially for women.
