Ok these comments are old so I’ve come late to the party. The ranking kick is a kenpo tradition. It is not a comment on someone’s martial ability. I would think the belt whipping situation is also a tradition as well. Nothing more nothing less.That isn’t what was being said, or implied, and it certainly isn't the only other option as you have presented it here as being.
Clearly you do not understand the realities of civilian violence, or realistic self protection, and I hope you are never asked to teach self defence to the elderly or children.
