I think people are born good and innocent, when you first see something like rape depicted it's horrible to see right? But then the next time it's less shocking.. And it reminds me of a poem."A vice is a monster of such frightful means, to be hated needs only to be seen. Yet seen too oft, familiar with its face, We first endure, then pity, then embrace." It's by Alexander Pope, but I modified it a little. I think we become desensitized to horrible things like rape and murder when they are depicted too often and especially for entertainment.
