I'm very surprised that a bunch of "open-minded" jiu jitsu practioners would be so quick to dismiss someone's opinion....
If he doesn't like making light of "crack-heads" more power to him. Same reason us pragmatic practioners don't try and look for the old Japanese terminology for every single move that has ever existed. It doesn't affect the validity or effectiveness of the move, or the system by what you call it. The beauty of BJJ is that there are no right and wrong, ultimately, just effective or not!
