Right. But it sounds a lot more to me, like an example of, "I've been hurt by people, so I'm going to attack people that I see as inferior to me."
It's this attempt by a few to create a heirarchy that I think leads to this. Not a lot different than a bully mentality in school. Usually the bully attacks weaker kids because when he gets home he gets abused by his parents. It's human nature to attempt to create a pecking order, and only natural to try to see where you fit into in society. In and of itself it's not even bad to do this, as it's a part of our competive drive as humans to better ourselves. However when someone is mentally sick, they use it as an excuse to lash out, and cause pain. It was a sense of superiority that has led to some of the most voracious and atrocious crimes throughout history. I think this person is just showing either a lack of critical thinking skills leading to an inability to see beyone their own ideas, or simply the rantings of a mentally disturbed individual.
