I’ve read some things that deal in sad/dark/actually depressing and disturbing subject matter. I’ve loved them and the points they make without endorsing the events portrayed.
It’s always disappointing to get online and see that the conversation is “X thing shouldn’t exist” on the grounds that it made somebody feel badly. It was meant to make you feel that way and it’s normal that it did - it’s okay that you stop reading it or don’t finish it but I am BEGGING you to consider why it made you uncomfortable and why the author felt the need (if the answer isn’t immediately obvious, as it can be). There isn’t shame in something putting you off so badly that you shelve it.
The sterilization of reality is a detriment to all who exist within it. To censor stories with painful themes is to erase the reality that such stories are based in some horrific truth and works to erase the reality that many people have endured.
This trend or whatever we want to call it has gotten so bad that I listened to an entire lecture from somebody about how awful a book was and how it shouldn’t exist at all, how the author was a terrible person for concocting it and how it hurt people. When I asked what the book was, this person not only could barely recall the name but HAD NEVER READ IT. I bought the book. I read the book. It accomplished its task beautifully and I found it to be a cathartic experience. I also understood how it could make people so uncomfortable and would never judge anybody for setting it down.
It’s okay not to like something and distance yourself from it. Remember that those rules apply only to you, though, because they speak only to your own psyche.
