I'm curious, did you attend a university Min?
I did and told one professor in front of the class that what he said was bullshit. Got an A in the class. I guess its not always the case that you fail. Did someone fail you for speaking out? It was never my experience even though one instructor said I was unusual because "No offense but the JW's he had taught weren't very intellectual nor intellectually honest." He was a prince, insert sarcasm.
