I didn't read anyone's responses to your post, so I apologize if I step out of context here, but; I was at that seminar, and don't see what came across as violent. It was quite laid-back and geared towards the basics from what I could tell. Was it Charlie McGinnis Sensei's classes? Yamada Sensei's? or was it the partners you trained with? Please elaborate for me, as I found this an incredibly enjoyable weekend of training (and yes, I engaged in some butt-kickage, but that was just with a friend or two, and all in good spirit).
