Touting the historic oppression of non-white groups as reasons to not discipline individual students poor behavior that would warrant such discipline for white students. (specific acts: stealing from other students, disruptive behavior). Claiming she would never marry a white person because of their evil works of oppression.
I note too, that not much learning went on in that class (speech and communications), which was more of why she’s my top worst teacher.
Yeah, it was traumatic for me as well. I didn’t recover any semblance of self esteem (nor did I date) until I was in college. The military was actually a boon for me. On the good side, I haven’t taken any shit from anyone since HS graduation. 
The one that sticks out in my memory was the Physical Education teacher who encouraged bullying and told the bigger kids to keep the smaller ones “in their place”.
Runner up was one in grade school who would regularly just leave the class for long periods, upon which everything went to hell and I usually ended up getting attacked by a mob.
One reason I never had interest in children was that I never wanted to send a child to the hell of school.
That’s a good question. It was like a relay. Half the girls waited on one side of the gym while the other half teamed up with a pair of boys on the other side. The teams ran from one end of the gym to the other and the girls were swapped out and the new teams ran back where they started. I don’t know how they handled if the numbers didn’t exactly match.
OMG - memories! Slightly different lyrics, but essentially the same.
Also:
Ta-ra-ra boom de ay!
We’re off from school today.
Our teacher passed away.
We threw her in the bay.
*She scared the fish away - *
they found her yesterday.
Ta-ra-ra boom de ay!
Ta-ra-ra boom de ay!
That’d probably get you suspended today.
My high school physics teacher was a right-wing nut job who would spend part of our class time whining about how he wasn’t allowed to show his faith in the classroom. Apparently he had put up a poster in his classroom once that was religious in nature and someone told him he had to take it down. We had to hear about that several times a week for the entire year. This was in the early '90s.
He would also not stop lecturing when the dismissal bell rang- he would make everyone sit there and listen to him for most of the passing period between classes. His next class was standing in the hallway waiting to come in and we were still sitting there getting harangued about how hard it was to be a Christian.
I was late to my next class more times than I could count but fortunately my next class teacher knew about Mr. C and his religious rantings and didn’t hold it against me. Probably helped that half of my physics class had the same next class together so we were all coming in late together.
We had a third grade teacher, Mrs. S., who actively seemed to hate the kids in her class. She had six children, all girls, and one was in our grade. The daughter was a nice kid, and a friend of mine. I found out later that her dad had gotten laid off from his job, the family was living on Mom’s Catholic grade school teacher’s salary and Mom was pregnant again. So I’m sure part of it was she was incredibly stressed out and not feeling well. Nevertheless, third graders have no concept of any of this and shouldn’t bear the brunt of her anger at the world.
There were many incidents, but one stands out. She gave us a book report-type assignment and said something like “We’ll talk about it again next Tuesday.” Tuesday comes and she asks us to turn in the assignment; we all looked at her blankly. Nobody realized she meant “It’s due Tuesday” because she didn’t say that. Not one kid had done it. So she took us in the hall, lined us up against the wall and went down the row, one by one, yelling in each kid’s face about how they were wrong and stupid and they should have had it done, etc. I remember thinking, as she is screaming at me, “If the WHOLE CLASS thinks you said something else, then you said something else. It’s not our fault, it’s your fault.” But I just stood there expressionless because that sentiment would not have been well received.
Halfway through the year she went out on maternity leave and we got as a substitute Mrs. M, who was the kindest, most caring and beloved teacher that school ever had and whose funeral a few years ago was attended by generations of former students. So that worked out for us.
Mrs. S. never did come back - her husband got a job in another state and the family moved. I kind of missed her daughter, but was relieved to be rid of her.
Have another example, a different variety of “worst”. In my Catholic high school, our history teach was Ms. D, who was young, attractive and flirted with all the football players. She called predominantly on the boys in the class and ignored the girls.
There was a married couple who also taught there, Mr. & Mrs. B. Mr. B was a biology teacher and looked like a sterotypical nerd - glasses, pocket protector, bad hair, the whole bit. His wife was petite and lively and well-liked but not as young or attractive as Ms. D. Mr. B and Ms. D began an open affair that the whole school knew about, to the point where they sat holding hands in assemblies while his wife sat by herself across the room.
As I said, this was a Catholic school and teachers are supposed to uphold Christian values. This includes not blatantly cheating on your wife in front of the entire (highly interested!) student body. The two lovers were both fired. Ms. B, now divorced, remained at the school until her retirement.
