I have yet to see anyone say that taekwondo has no connection with karate, in this or any recent thread. What we are saying is that taekwondo (Kukkiwon anyway) isn't a karate ryu and that teaching methodologies differ.Obviously there are some that believe that Taekwondo and thus it forms/poomsae have no connection with karate and thus the historical basis I and others purport cannot be true - despite what we say or what evidence we give. Okay, so don't accept what we say (mine through much research) but how about the word of one of the most influential men in kukki TKD: Chong Woo Lee?
As for techniques being 'karate techniques' they're just techniques. There are stylistic differences, but every unarmed fighting system addresses strikes and defenses, be it west or east, Japanese or Korean.
There is no question that taekwondo is related to karate, just as karate is related to something else, probably Chinese.
