I've just read an article I'd like to recommend but it's really impossible to offer an excerpt that will give you a good idea of its message. Here's the title:
Conservatives Live in a Different Moral Universe -- And Here's Why It Matters
And the lead is this: "Liberals and conservatives have highly different moral priorities. And we have to understand them if we want to accomplish anything."
It's very thought provoking - as are the comments that follow.
