NOT P but DFW on Updike

[Mike Jing]

The following excerpt is from David Foster Wallace's review of John
Updike’s *Toward the End of Time*:

       “Just a penis with a thesaurus.”
       “Has the son of a bitch ever had one unpublished thought?”
       “Makes misogyny seem literary the same way Rush makes fascism seem
funny.”
       And trust me: these are actual quotations, and I’ve heard even worse
ones, and they’re all usually accompanied by the sort of facial expression
where you can tell there’s not going to be any profit in appealing to the
intentional fallacy or talking about the sheer aesthetic pleasure of
Updike’s prose. None of the other famous phallocrats of Updike’s generation
— not Mailer, not Exley or Roth or even Bukowski — excites such violent
dislike.

Does the "Rush" here refer to Rush Limbaugh?

Also, what does "appealing to the intentional fallacy" mean here? Where is
this "intentional fallacy" exactly?
