Ridiculous
Most so-called "scholars", Biblical and otherwise, are full of crap. You don't get tenure any more by analyzing the writings of Moses, or Shakespeare, or Homer. That's so old-school. You have to "prove" multiple authorship -- the more, the better. Otherwise, we might have to admit that some people make the rest of us look like mental and/or spiritual wanna-bes. And we can't have that, because we're all equal. (Except for academics, who are of course smarter than everyone else.)
Alternatively, you can "prove" the author was secretly homosexual (or communist, or atheist, or feminist -- or racist or sexist, if you don't like him), by analyzing "hints" in his/her writing. Never mind that millions of people have read that author and never come to that conclusion. Your perverse interpretations are based on the latest "scholarship," which the hoi-polloi can't be expected to understand.
This opinion of mine will be blithely dismissed as "anti-intellectualism," even though I have a real PhD and do real research for a living.
