That's 100% what I meant by my hardass professors, because a vast majority of them did exactly what you described. On top of that, I said "genuine" previously because they would scoff at a student's work in class, say "this isn't worth my time", and move onto the next one. That was the "genuine critique" and no one was given any breathing room for the sake of equality or whatever and us students were conditioned to desire that "feedback" :(
