Yes editor-one put it nicely.
Ultimately though if you use this experience to inflate your ego about how smart you are you will fail to grow from it. I would recommend avoiding that trap that the public school has lured so many NPs into, and growing from the idea that people are different.
I was criticized by my english teacher for treating people like concepts and treating themes like a playground built for my entertainment. This struck me as a direct criticism of my soul at the time, but in retrospect I believe I have started to understand that many people live in a much more "real" world than me and that my theories bother them when they perceive more pressing issues.
You have to meet people half way
I'm guessing this really is in response to my post-- So I'll clarify.
I had a teacher in high school, years ago, give me a B and my partner a B+ on a project in which I had done literally 100% of the work.
There was no reason our grades should have been different and no reason my partner should have received a higher grade than myself on a project he put no time or effort into.
My partner and I went back to her desk after class. We told her that I did the entire project and I asked her why there was a grade difference, etc. She pretty much told me to go pound sand and she'll do what she wants and all grades are final...
So what I learned from this is that people are different and that emotional people who hold grudges (she brought up abortion earlier in the semester in math class and we had a mini debate and she didn't like my views/arguments) will attack you in unrelated areas to make themselves feel better and regain "superiority."
Another example of someone "teaching me a lesson" revolved around a college professor who couldn't quite tell me what I was doing wrong. It was in a "sociology of geography" class and the professor gave me a B on my photo essay. The essay was on order vs. disorder in Philadelphia (social constructions of course, because in liberal arts, everything is a social construction-- even genetics... but I digress).
She pretty much decided that she didn't like me taking and juxtaposing a bum (who happened to be black) with a cop (who happened to be white). When I talked to her (I spent many hours at her office) she kept going back to that picture. My theory is that she doesn't like white men (she happens to be black feminist) or what she saw as a white person bringing race into a project. The only other white guy in the class also received a poor grade. I was privy to hearing both her and his arguments about his collage and accompanying paper he had created about his neighborhood in Philadelphia. The reason she gave him a C was because she argued his neighborhood that he defined didn't exist (not like it really should matter if a neighborhood is recognized as existing or not, everyone has a different definition of their neighborhood and she never told us that it had to be a recognized neighborhood... as long as you can define your neighborhood geographically, it should be clear what area you're referring to). She argued that his neighborhood boundaries weren't official and that's why she gave him a C. She backed this up by going to about.com as a reference (which had about 10 neighborhoods for the entire city of Philadelphia). Alternatively, he went to the U.Penn and Philadelphia Planning Commission websites, which he had sited on his accompanying paper. The boundaries he had in his paper matched the PPC and U.Penn websites... Anyhow, it pretty much came down to she didn't like him or me. It was pretty funny to watch a supposedly Ph.D prepared person take "about.com" as an authoritative source over U. Penn...
I worked on her all semester (going to office hours and trying to form a relationship (and massage her ego), which I did since with feelers it's more about your aura (smiled and was very friendly) and presence than thoughts-- unless your thoughts piss them off, that they will remember), but I made a mistake. I told her during one of our chats that I really wanted to get an A in the class... she responded by saying "I made a lot of B's during college"-- After that short little jab, I knew I would get a B... My fears were finalized when I received my final grade of an 89.5% with no roundup...
She taught me a lesson, that there are some people who aren't worth trying to convince or win over and that they will hold a grudge against you for who you are, not what you produce. They will dislike you for your sex, race, and stereotypically enjoyed "white privilege," etc.
The math teacher taught me that if you speak your mind, certain people will try to put you in your place if you make them look like a fool even once in a totally unrelated field.
So yes, you learn when to open your mouth and when to shut your mouth... that's my advice... read the situation.
If the teacher can't explain in detail a valid criticism then it's most likely not you... especially if they are coming at you in a condescending tone.
Obviously, the actions of the teacher has upset the original poster enough and isn't normal behavior from his other teachers, so they've posted the issue on this forum.
Life ain't fair... tell them what they want to hear and move on...
... My biology teacher didn't want to approve me for chemistry because she thought I would blow shit up with my absent mindedness. You are most likely going to have to steer clear of heavy machinery like printing presses. The fact that you got your A does indicate she thought it was a good effort, so her motives lie elsewhere ...
