Your opinion is a little short on content. Medical Degrees? Overall Risk studies? You want to ban square dancing in shcools where partners swing with locked elbows? Risk to the shoulders?
Do you have any medical degrees? I have trained with various medical professionals, all of whom disagree with your opinion.
Do you have any rank in a martial art that would qualify you to teach children? Many of the people posting here not only have extensive degrees in many arts, but they have also at one time or another, taught and or raised children.
I don't (and I don't believe others have) suggest **banning** anything except **you** teaching wristlocks and dancing to young children under the **pretense** of effective self-defense.
Your response to the posts in this thread speak volumes as to who is short of what.
I see no progress has yet been made...
