If you are able to infer anything about what the author thinks postmodernism is then you are a much deeper thinker than I am. I will give the author credit for (exactly) one thing. They used the word postmodernism but didn't define it as a box containing everything they don't like and perceive as less than 100 years old. In that sense, they are better than tens of thousands of other internet essayists. Might want to lay off the DMT though.
