First, congrats on your imminent degree.
Second, popularity has never been a determinant of fact. Not so long ago the experts all knew that atom could not be split and the world was flat.
The trouble is that academia and administration are increasingly populated by grey people who don't enjoy variety. So if your professor is one who "knows" that something is true, then some would say that you are well advised to "know" the same until you get your grade. It seems that "expediency" is how truth is reached in this wonderful modern age. ;-)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
