I am not considering Karate as a homogenous. This is why I have made the comments about grappling in regards to Karate. I have limited experience in pure Karate but a modest amount in Shotokan. I agree with you on there being little grappling in Shotokan. Like I said, there is a lot to talk about on this question. Clarifying as you did that there are several derivatives is a very good point. I am certainly not taking sides with anyone in regards to this thread. I have simply done what everyone else has and cited what I know from my own experience.
