Let's see...
1) In 10th grade I had a biology teacher who was a creationist, tried to sabotage lessons on evolution, refused to acknowledge several students when they wanted to avoid dissections for moral reasons, even though state regs require him to provide them with an assignment of equal workload and credit, to the point where I confronted him in front of the class and told him that if he didn't change it I'd notify the head of the schools department as well as report him for violating state regulations. Not to mention that he rarely carried his gradebook with him, frequently neglected to record information, rarely looked at what was handed in, and every class was him reading off of premade overhead gels or putting in a video.
2) In 7th grade I had a social studies teacher who would rarely mention assignment due dates except on the day assigned and the day due, even if the assignment was a 2 month thing or something similar. She also saw a student reading in class, tore the book from his hands and hurled it at the wall, someone else shouting 'Duck' is the only reason why said book didn't hit me. She also offered tutoring to students who had trouble, however she put them on a lower priority than talking to people on the phone and other things, then, after the time had passed and the student was still having trouble would say 'well I helped you in tutoring' no, no she did not.
3) I had a HomeEc teacher in 6th grade who was a militant vegetarian, not only did she insult anyone who ate meat she put up stuff from PETA in the classroom but she also put up graphic pictures of animals being slaughtered and stuff written from 'the animals perspective' in a means to make us go to a 'more moral' position and if anyone said anything she became self righteous and said that we had no right to judge her behavior.
4) In 7th grade I had just had someone grab my hands and empty two hot glue guns onto my palms, causing them to become giant blisters, my math teacher told me that I could either take the test with hands that could barely hold a pencil without the plisters popping or me turning anything I made into illegible scrawl or I could get a 0 for the test, please note that she saw my blisters, she simply said that it shouldn't matter.
5) In College I was in a humanities course where the professor (oh and this is a non religious school btw) spent most of the classes talking alternately about what a wonderful and kind and great person she was and all that and how Christianity was the only true religion and any other religion in the world was made up by demons. Also that all Muslims needed to publically apologize to the citizens of the united states and that all atheists are amoral monsters who would murder the moment they got the chance. She also banned recording devices in class, for those wondering why she was still teaching.
6) In a different college, after transferring from the former one, I was in a political philosophy class where one student had to miss a week because her mother had died and she went back to attend the funeral. The professor does not accept papers by email. Well, the time she (the student) was gone the papers were due for an assignment, she got it back as soon as she returned, the professor told her "You get half credit, and be grateful that I'm generous enough to offer that' in front of the class. Oh, also if someones cell phone went off she would dock everones grade 5 points, and she did a random spin wheel to determine if there would be a pop quiz, and if she felt we went too long sans quiz she would say 'too bad, you get one anyway' the last one is more weird quirk, but still.
These are all the ones I can think of off hand
