I write papers that the teachers want to read, I do not change my opinions. I merely cater to their needs to make them feel like they have changed someone to their thinking. I get good grades because I am smart enough to know how to BS a paper.
If a student disagrees with the professor, the student failed. This bias is obvious in the class i am in right now. The more liberal friend that I studied with got 15% better than I, and this class is the first he has ever beaten me. If my brain does not mush into the mold that has become what is politically correct I will be caste out of academia.
