This might sound gate-keepy and elitist (and, y'know what, it is, and I openly admit to it because I don't think it's necessarily bad), but I 100% agree. Not all reading is quality reading, and if you're just rushing through whatever YA novel is hot right now, it's not the same as sitting down and reading literature. Or working through dense non-fiction work à la Adler. It's nothing more engaging than binging Netflix or Marvel movies, but they certainly think it is.
It's also funny as this reminds me how little r/books actually talks about books. It's mostly validating each other for never challenging themselves, and - shock - "I read a classic and it's actually good".
