If you want to do only research than be a researcher. Universities and labs hire plenty of them. Professors do research and teach. It's a part of the profession. The requirements of being a professor aren't exactly a secret so there is no excuse to being a shitty teacher if teaching is literally a component of the job. The universities that pay their salaries and the students that pay the universities should demand more from their professors. If students get poor grades for not understanding the assignment then it is only fair that bad professors get a poor review for not understanding the assignment.
