As I mentioned, I don't use the title "professor" because the connotations in English make it seem pretentious to me. That said, I figure those who do use the title are just going along with traditional usage from BJJ's country of origin, so I don't judge.
Similarly, I also find the titles "master" and "grandmaster" to be pretentious. However, I recognize that in many Korean arts those titles are official ranks set by those in charge of the art and so I try not to judge KMA instructors who go along with the convention.
