Nick, thanks for the back-up, bud. The problem with a "'roid rage" guy like this isn't his words or his lack of understanding of aikido, (for instance, his statement "gokyu but still beginner's mind" - Duh, gokyo IS a beginner, Drew!) it's that he doesn't see these faults.
This type of person always hurts someone on the mat, and leaves a trail of injuries. I doubt he works out with the senseis he mentions - they wouldn't tolerate that behavior.
