Economist Arnold Kling argues that Progressives, Conservatives, and Libertarians each have their own language and way of looking at the world, making it easier for each group to demonise the others, resulting in ideological intolerance and incivility.
Speaking on the EconTalk podcast, Kling explains:
What I claim is that Progressives organize the good and the bad in terms of oppression and the oppressed, and they think in terms of groups. And so the good is to align yourself against oppression. The second axis is one I think Conservatives use, which is civilization and barbarism. The good is civilized values that have accumulated over time and have stood the test of time; and the bad is barbarians who try to strike out against those values and destroy civilization. And the third axis is one I associate with Libertarians, which is freedom versus coercion, so that good is individuals making their own choices, contracting freely with each other; and the bad is coercion at gunpoint, particularly on the part of governments.

By understanding the mindset of others, Kling suggests we can do a better job discussing our policy disagreements and understand why each group seems to feel both misunderstand and morally superior to the other two.
