Agreed. I see it in TJMA, with instructors introducing themselves as “Sensei Smith”.
That would be AJMA, for Americanized Japanese Martial Arts. These are people that train in a traditional Japanese martial art, but no longer have a real connection with Japan. This means that they do what they consider correct, rather than what would actually be considered correct if their art was still Japanese. Anyone with a living connection with Japan in their Japanese martial arts knows that a person NEVER introduces themselves by a title such as sensei. In Japan, honorifics are bestowed by other people and never bestowed upon yourself, thus you might introduce someone else as Smith Sensei, but never yourself. Another easy mistake a lot of these same folks make is that the honorific always follows the name, and never precedes it.
