And I highly doubt you have any idea how much of an understanding of BJJ I have. I'd suggest it's a fair bit higher than yours, though, for a range of reasons (no matter what names you throw at us), as your posts seem to increasingly show a lack of understanding of many basic aspects of different systems, as you can't get out of the small context you have in your head already.
Yes, I'm sure you believe you know more about BJJ, korean martial arts, japanese martial arts, all martial arts really, than I do.
