Dara Lind anoints them "Barders":
[J]ust as much of Obama-skepticism is motivated by the belief that a black dude could not possibly be legitimately qualified to edit the Harvard Law Review or become president of the United States, much of Barderism is motivated by the belief that a man from a small town without a university education couldn't possibly have written some of the best literature in the English language.
Barders will frequently argue that the references to, say, falconry or court intrigue in Shakespeare's plays could only have been written by an aristocrat, or that no one would be able to write as intelligently about law as Shakespeare did without a degree from Cambridge or Oxford. The snobbery of this is pretty obvious — it's as if the Barders had never heard of an autodidact before.
