Thank you for providing an excellent example of how people react once that "enemy" box that I was talking about gets triggered. "It's not my fault you were raised" etc is a perfect example of how people talk when they think they're talking to an "enemy," and attacking is more important than anything else.
(Mao also thought that killing all the birds would help the agriculture, I don't really take him as any kind of authority on how stuff works. MLK Jr. would have been a better example.)
