I'm a bit confused by a few points in your response, which seem to indicate a pretty unilateral understand of what it means to believe in or practice a religion.
The confusion is to be expected since this is the most confusing aspect of human existence.
First, why must human knowledge necessarily proceed on two opposing fronts? <snip> I highly doubt that all religious people unquestioningly follow the direction of those in authority.
I don't think that knowledge should proceed on two opposing fronts. All deistic religions believe their deity also created the universe. If theology (the foundation of religion) is the study of the Creator and science is the study of what was created how do we justify different approaches to theology and science? It is not enough that individual scholars do not unquestioningly follow the direction of those in religious authority because of personal convenience. To countenance the dichotomy between theology and science is unacceptable.
Second, not all people (professors included) leave their free will and freedom of expression at the door of the Church/Mosque/Temple/Shrine/What-Have-You.
By definition you must. If you accept the notion of heresy you do.
Third, I don't understand what you mean when you say that the "collective development of the race" is hampered by religious belief.
MY quarrel is not with religious belief but with the practice of religious belief which naturally divides us. We have not basis for accepting the notion that a small cadre of humans are superior to the rest of us humans and are uniquely qualified to stand between us and our deity as His/Her representatives. This is as illogical today as was the geocentric concept. (And I speak as one who was trained for the clergy).
Fourth, if you can figure out a definition of "the correct understanding of human knowledge," please, let me know. Philosophers have been beating their heads against the wall on this one for millenia.
For starters we should agree that since human knowledge is derived from a study of an integratee universe then this knowledge should not be fragmented. (This was discussed in a CHE article in 2004.

I first looked for such a topic in this section. However, the focus of that thread is slightly different from mine.
