It doesn't, really. It labels a person a "social media poster who identifies as a reader" based on them passing negative judgment on difficult books ("fundamentally fraudulent") and those who read them ("anyone who would read such a book must be pretentious, phony brodernist snob").

Sure, there is the middle part ("books are supposed to be fun and the world is so awful why would you want to suffer"), but I took the bit about negative judgment to be the main thing the author was complaining about.
