God forbid you call the professor out for being an asshole without being kicked out of school
If one truly thinks that of one's professor, why would one want to remain at the school? If one's opinion of one's instructors/professor(s) is so low, one should be indifferent about being there to take their class(s). Moreover, one is, in college, an adult, which means one is there by choice. If one is dissatisfied, one should leave.
Because the professor works for the student, not the other way around.
If a student has debt and is 3/4 of the way through to their bachelor's degree and already has $70,000 in debt, the student has every right to call the professor an asshole if they want.
Well, you just keep thinking that....In the real world, consumers don't buy discretionary goods/services with which they have become dissatisfied. If one is dissatisfied, say, with one's attorney, doctor or accounts, one may call him or her an asshole, but in doing so, if one doesn't terminate the relationship, the professional quite likely will.
