Even if it were true, the childish "but they do it too!" response does not justify Dini's bigotry.

So is it bigotry when a professor fails a student who clearly hasn't done the work to pass a class? It's up to the student to retain knowledge and understand it. If the student chooses not to, that is his problem, not Dini's.
