Ep 1. Stunning and Brave

In the season 19 premiere of South Park, titled "Stunning and Brave," the show takes on the issue of political correctness. The episode starts with a new principal taking over at South Park Elementary who is very focused on promoting political correctness and sensitivity to all cultural backgrounds. This leads to a new set of rules being implemented, such as banning Halloween costumes and replacing Thanksgiving with a "native appreciation" celebration.

Meanwhile, Randy Marsh has started a new business selling "gentrified" food, which he claims is healthier and more politically correct than traditional fast food. However, when he discovers that the health benefits he's been promoting are actually just a marketing ploy, he tries to cover it up and becomes embroiled in a scandal.

As the episode progresses, the focus shifts to the newly-introduced Caitlyn Jenner character, who is depicted as a hero and icon of political correctness in South Park. However, when Cartman is banned from the school assembly for not being politically correct, he decides to take matters into his own hands and exposes Jenner's "secret."

Overall, the episode touches on a number of hot-button topics surrounding political correctness, including cultural sensitivity, gender identity, and the role of marketing in fueling the trend. While the humor can be crude and controversial at times, the episode does offer some interesting insights into the dangers of blindly following political correctness without questioning its underlying assumptions.
