I think the paper's thesis is probably completely wrong, but the idea is still very interesting.
Because I doubt most conservatives have any idea what lefty social science profs are doing, either in their research (which few people read) or in their private lives.
Many leftists have seen - and still see! - academic economics as a political enterprise devoted to supporting libertarian/free-market ideas and business interests.
It was pop economics, not academic econ or econ academics, that they were (often justifiably) reacting to.

And friends on the Right send me links to lefty-sounding sociology and humanities papers all day long.
