Being able to disagree is a dying art – and a vital one:

To say the words, “I agree” — whether it’s agreeing to join an organization, or submit to a political authority, or subscribe to a religious faith — may be the basis of every community. But to say, I disagree; I refuse; you’re wrong; etiam si omnes — ego non — these are the words that define our individuality, give us our freedom, enjoin our tolerance, enlarge our perspectives, seize our attention, energize our progress, make our democracies real, and give hope and courage to oppressed people everywhere.

Diagreeing civilly and productively is what makes representative government possible.  We’re losing that ability.
