I would remind you that extremism in the defense of liberty is no vice. And let me remind you also that moderation in the pursuit of justice is no virtue.

What is objectionable, what is dangerous about extremists is not that they are extreme, but that they are intolerant. The evil is not what they say about their cause, but what they say about their opponents.

The world acquires value only through its extremes and endures only through moderation; extremists make the world great, the moderates give it stability.
