First, they do not claim that they do not understand the argument that the pomo theorist is making *with the misappropriated scientific theories*, just that they are not experts in the writings of the authors in question.
Second, their undertaking is perfectly respectable. Imagine if some nutcase were to take Max Sawicky's writings about profit rates and earnings, and used it in an obscure racist tract, made bogus claims about what Sawicky's writings concluded, and used it to shore up a load of opaque nonsense. If Sawicky were to condemn the appropriation of his work by saying that the author did not understand it, Sawicky would be under no obligation whatsoever to "understand" the rest of the nonsense. It would be enough to limit the critique to the use/abuse of Sawicky's work.
Heartfield has this one right.
