I've said this before, but what bugs me is that we as a society fail to recognize that every other human being on this planet is as complex as we and our loved ones are, and that we tend to write off people very quickly based on one or two things they do. Once we really take in the idea that every person's life is as important to him or her as ours is to ourselves, and deal with them recognizing this, we will be better for it - and I do feel the cruelty of much violence and humor desensitizes us to empathy with other people and behave towards them as if their feelings and existence were disposable.
