We don’t call R-rated movies “banned” because we’ve decided not to show it at schools to kids. That’s why it’s confusing when we switch to books and the word “banned” means somebody, somewhere, decided it wasn’t appropriate for kids in their school or something like that.
If someone opened a banned speech museum and then it turns out most of the display is just spam comments from HN it would be pretty silly and rightly criticized.
