Define "PC". You can't because it's an ever-moving goal-post, driven by whatever someone decides they're going to wake up and be "offended" about today.
It's not even "PC" to point to a written moral code (especially religious ones) to attempt to use them as an objective measuring stick on whether or not someone has done something truly harmful to someone else.
Many rely on "the law" as a measuring stick to avoid being called "anti-PC" but legal systems are rarely truly moral or anywhere close to equally just, when you get right down to it. It's only "PC" to say so, in regard to race, however.
Say "the law" treats minorities badly? You're PC.
Say "the law" treats those with money better than those without? Mildly not PC.
Say "the law" treats those politically connected and political leaders completely differently than those who aren't? Getting close to being anti-PC.
Say that's completely normal and politicians and friends buy their way out of having to be law-abiding and investigate themselves and find no wrongdoing? Whoa, now. We were all taught in school that our system of Justice is wonderful. You get back in line, you crazy anarchist/conspiracy theorist!
There's better examples, but "PC" is a joke, because it's not measured by any consistent objective measure. It's measure by popularity. Which ironically, really is anarchy to a degree. Perfect democracy is nothing other than a popularity contest and a horrible way to set policy.
But then, Republic is just a nice way of saying Oligarchy, too.
