You're absolutely correct, Makoto. I wouldn't argue with anything that you've said.
The problem is simply this: Is this persecution complex, this need to find something to concern yourself over, is it caused by the society we live in or is it a side-effect of being human?
On the assumption that society implants fear and argumentitive natures in its people, we can fix that, and it will likely remedy itself anyways. But, if it is humanity, there's nothing we can do.
