Most teachers are leftists, and leftists are petty and vindictive.

I worked at a handful of different schools when I was 19-23. So basically right after I finished high school myself, still very much having the perspective of being a student.

Totally changed my perspective on teachers and that was long before I was thinking about things being woke, leftist, or whatever. That's been close to 20 years ago now and I've still never run into a work group as petty as teachers. Not even close.
