It isn’t surprising that this was an “educator”. I don’t mean all people in education are like this, but in my experience some of the most unprofessional people I’ve ever known were teachers. And that was from 45 years ago so I can’t imagine how bad it is today.
That’s opposite my experience (high school/college 1971-1978 central-northeast PA). I recall nearly most, and likely all my teachers/educators to have been very professional, mature, adult-like, caring, and who set good examples in attitude, dress, and conduct. That’s what I remember, what it was like back then, at least in my little corner of the world.
