I'll quote myself from a post earlier, because I don't want to type it out again, nor do I want to think further on the topic.
"What it really boils down to is the exclusionary attitudes we as a species have. We ignore people when we are made uncomfortable. We isolate people when we don't understand them. We remove any emotional attachment that they too, are human beings and need to feel loved and supported.
We as a society fail on that and many other areas. Our burden because of our failures is watching children get gunned down on national TV."
