Quote: I love getting even when I get screwed by someone. ... Always get even. When you are in business you need to get even with people who screw you. You need to screw them back 15 times harder. You do it not only to get the person who messed with you but also to show the others who are watching what will happen to them if they mess with you. If someone attacks you, do not hesitate. Go for the jugular.

How American conservatism has come to this point is very interesting historically and psychologically. But of course that is rather like saying the holocaust or the bubonic plague or Russian pogroms are interesting subjects of study. They are.
