Can't say much for political correctness, since politics is rarely ever about being "correct".
It could be historically corrected though.
As someone with centuries of family history working within the church forwarding its influence across europe, while quietly preserving & documenting the old ways and history, it's easy to recognize that majority of history as presented in the West conveniently glosses over & is tweaked to support a rosy & church-serving version of reality. I just wish more people took some effort to learn a little about their faith, their book, their church, their heritage, and where & when all the interesting bits & pieces come from. ...before getting bent out of shape arguing about it.
...but as a huge Peanuts fan, I'm happy to let it pass. I even took some design work on Charles' residence at a loss just to be able to meet him. Good fun. Neat guy. Great series. Can't wait to see it.
