How is it comical? I've trained BJJ for awhile now.
And no, they teach you to respect and be humble before anything. If Cantwell went to any accomplished BJJ grappler from Brazil with the same atittude he showed on UFN, he would get eaten alive. BJJ is a very prideful pratice where you have to be humble during all your teachings.
Do you see accomplished fighters like Nogueria, Fedor, Randy, Hughes, GSP, Anderson Silva conduct themselves like that after they fight?
