Implicit in complaints about political correctness is that it (the statement, term, belief) is logically incorrect or at best misleading. It then follows that a deliberate logical fallacy creates aesthetic problems in essays or speeches or works of art-- or whatever the PC thing touches. In short, PC feels stupid just like any bad logical leap, and is therefore ugly and distracting.
That thought came to me while listening to a decent podcast from the BBC called "Living with the Gods." It's a series of 15 minute episodes about some of the core aspects of religious belief throughout history and across culture. The first several episodes are great, and generally it's way above average for podcast/radio shows, but I score it a mere "decent" thanks to commentary in several episodes that is simply PC bullshit of the 2017 vintage.
