The biggest one I can think of is The Catcher in the Rye. It is a good book, and if someone likes The Catcher in the Rye it means they are well-read. If someone says it is their favorite book then they probably identify with it too much and missed the point.
What are some other examples of this that you know of?
Anything by nietzsche, sartre, or camus.
Three of the most famous philosophers? How would read their works be “problematic” or make you a bad person?? People literally study them in school and university.
Imagine saying , let’s not study anything than Einstein ever did because he was problematic.
What a stupid thing to say.
