If I preached unity, I must act like a unifier, even at the risk of perhaps alienating some of my own colleagues. - Nelson Mandela
If you say you're a unifier, you expect and usually get applause. I'm a divider. Politics is division by definition, if there was no disagreement there would be no politics. The illusion of unity isn't worth having, and is anyways unattainable. - Christopher Hitchens
