Yes, because it is imperative to teach and learn by rote. If any idea is commonly held to be true, there is no reason to have any discourse. Even for ideas that seem to be binary this is just ridiculous -- you will note that this position would preclude discussing topics and discoveries regarding a round earth, DNA, electricity, and many other understood "truths" over human history.

Discourse and unpopular ideas drive discovery and learning more than memorization ever will. It does not mean that unpopular views are "right" it means that the act of understanding, listening to other perspectives and being able to construct your own beliefs in that discourse is a net win and absolutely core to higher learning; even if the unpopular view is garbage.
