In regards to your point about the physical size being a thing:
I worked at an inner city school and one of the teachers that could get students in line like nobody else was a 6'5" 275 lb man who worked as a biker bar bouncer on weekends.
This was middle school, so maybe the effect was exaggerated, but he could stop fights like no other.
To your point about trying to gain the approval of students, the dynamic definitely makes a big difference. Teachers that tried to be the 'fun' teacher were taken advantage of time and time again. I wish this wasn't the case, but an authoritarian role was the best way to provide consistency, stability, and true opportunity for learning in these types of classrooms.
