My first term of university I felt my professor downgraded my paper only because I disagreed with his point of view. The more my writing and structure approached perfection with subsequent papers always taking a different side than held by the professor the more the papers where downgraded. I would have stayed in school if I studied a STEM field as it isn't opinionated, at that level at least. I felt that if I stayed with arbitrary grading either I agreed with and showed all professors reverence or I would not do well in school. The professors can really shape how young adults think.
