"I think the only way one can really determine whether extremism in the defense of liberty is justified, is not to approach it as an american or a european or an African or an Asian, but as a human being. If we look upon it as different types, immediately we begin to think in terms of extremism being good for one and bad for another, or bad for one and good for another. But if we look upon it, if we look upon ourselves as human beings, I doubt that anyone will deny that extremism in defense of liberty, the liberty of any human being, is no vice."
