I enjoy reading unreliable narrators, and so while you’re totally correct. Holden is nothing more than an angsty privileged teenager who is angry at the world. That’s what made the book fun for me, at a certain point his self serving lies and his cringe attempts to act like an adult are just funny.

I’ve found it’s a good litnus test for people, just like Fight Club or Rick and Morty. You’re absolutely allowed to like these pieces, but if you think those charcters are admiral than it’s a super duper red flag.
