Lots of shows are blackpilled. Blackpills are written into all forms of media, from books, TV/film, games, music etc. And have been for centuries. Just typical tropes such as the ugly person being the villain, or more often being the butt of the joke, always having the same unattractive features and being treated poorly. The reason for this being that it makes sense to people. It's often written into comedy because it's relatable to most people and they find it funny. Otherwise it wouldnt really make any sense to do so. It's just something people are aware of, atleast subconsciously. Hence it works its way into written works.
