Just look at the visceral hatred that Republicans have for Democrats (and vice versa to a lesser degree, I think). People brand themselves in ways that are exclusive and isolating and, ultimately, hostile.

It's not just in the world of politics but in the world of dog runs, where dog owners form into cliques that are quite hostile to each other.

Hard to see how people will get away from this kind of "group think" from which all hostility arises.

Okay, here is another example. Look at how much the Tea Party and Occupy Wall Street have in common and yet they each consider the other to be the enemy.

Having said that, I hope the author is right and that I am wrong.
