My comment to the teacher would have been:
If you are willing to present such a untruthful thing as a fact what else are you going to teach in this class that is a lie or non-factual? AND you want me to pay good money for this class?
Seriously! Are you really looking for a lawsuit against you for not delivering what you are being paid for? That is a truthful, honest and non-biased course of education.
The teacher’s response: BWAAAHAHAHAHAHAHA!
