I feel like the proliferation of graphic content speaks to the lessening of taboos in certain cases. There is a long and colorful history of things being omitted from manuscripts during publication (abortions, homosexuality, etc.), or being kept "vague" because the book would have no hope of being published if they were outright about it. I think it's great that certain themes are allowed to be explored more fully these days. It helps break stigma in some cases. Just looking at the other side of the coin.
