Keep in mind that at least the Sokal prank wasn't an attack on pomo per se. It was an inkling and subsequent confirmation that pomo editors could not tell the difference between highly technical jargon that drives home a larger theoretical point, on the one hand, and highly technical jargon engineered specifically to serve no purpose whatsoever.
Imagine submitting a large patch to the Linux kernel that references various files and line numbers but makes no additions or subtractions to any of those files. If you could feed such a patch all the way up the chain and get Linus to accept it, you'd have a pretty good argument that something is fundamentally wrong with then intellectual endeavor of Linux kernel development.
