Once you realize that other groups are coming from a different place than you are, you actually can empathize with their views. It may not be as fun, but you can actually view your ideological opponents as decent human beings who look at the world differently from the way you do. And it shows the foolishness, other than for therapeutic catharsis, of yelling at your opponents oblivious to why they don’t understand the wisdom of your views. The person you’re arguing with just doesn’t see the world the way you do.
We are like the blind men and the elephant where the elephant is some social problem. We grab hold of one part of the problem and fail to see that the world is more complicated.
