Right-Wing Polemic Books Are Pornography; Left-Wing Polemics Are Michelangelo's David
              Broad-minded 
St. Louis Post-Dispatch blogger 
compares Obama Nation and Unfit Command to pornography, building a facile syllogism to support his metaphor.
No comment on McCain or Bush hatchet jobs, and the author says he doesn't read the books because he doesn't like peep shows, either.
Except that, of course, the books offer ideas instead of naked pictures.  But the 
Post-Dispatch intelligentsia doesn't need to actually read books to tut-tut the wrong thinking within them, doesn't need to actually answer arguments when --hey! Look!  Straw man!
I don't care for the books myself because they tend to be facile and unconvincing.  Kind of like 
Post-Dispatch analysis.
