Jonathan Haidt TED Talk
I just found this today, I'm so glad!
To anyone who enjoyed the guy's essay, here he takes 19 minutes to beautifully lay out his thinking on moral psychology and how it relates to liberal vs. conservative.
If you watch this 19 minutes you will never ask "What is wrong with you people" again. You'll know what's wrong -- and you'll be amazed to find that you are wrong, too, and that every culture in earth's history is proof of it.
Try it, you'll like it!
