wrong and right

If a black man is racist, is it okay, if it's the white man's racism that made him that way?
Because the bully's the victim they say. By some sense they're all the same.

Because the line between wrong and right is the width of a thread from a spider's web.

I could tell you to go to war or I could march for peace and fighting no more. How do I know which is right?
