Now before you start sending me your hate mail, read this guy's post:

I am only quoting him.

My favorite line in the post: "This is the kind of behavior pathological social-ladder climbers learn to perfect early. This is typical of  what the Canadian thinker John Ralston Saul calls a "courtier" or a "Voltaire bastard"; a man who either has no opinions of his own or is perfectly happy to substitute them with anything that can advance his carrier, create new friends that can advance his carrier or open doors to new carriers or new revenues."
