All art criticism is political because all art has political implications  Clearly, the critic who chooses to address overtly an artwork' s political implications is engaged in political discourse
But those critics who attempt a purely aesthetic evaluation of a work, and ttherefore ignore the work' s political implications, necessarily, though perhaps inadvertently, end up endorsing the politics of the artist
Art criticism that is intended to evaluate a work on purely aesthetic grounds never ends up rejecting the politics of the artist whose work is under review.
