I won't kid you - many of the talks are PC love ins but there are many that hereticlly aren't. If you have twenty minutes a pop watch this video on Psychology or even Billy Graham talk about morality. Powerful stuff. For a backhanded defense of conservatism see this video of the five pathologies of humans (liberals only obey 2/5, but like his paper this is at best a neutral thing) or the blander video of things you misunderstand, but are sure of. Self deception is built into humanity; knowing everything is too expensive to tolerate.
If I did a TED..
If I did a TED talk it would be titled "The Great Man Theory of History: Why You Aren't That Fucking Neat.*" I believe there really are men in history that weren't simply replaceable products of their time. On the good end are Washington and Churchill, in the middle are Hamilton and Bismarck, and at the sweet-n-sour end are Robespierre and the French generally. It isn't useful to put Stalin and Hitler in play because if your conversational partner thinks they are in play then that person is out of bounds.My friends, family, and acquaintances are some of the greatest and happiest people ever to walk the face of the Earth -- this belief is one of the hallmarks of a conservative. I have no problem believing in the good works of men and enjoy the exceptional works of man. I also have no problem believing in man's inhumanity to man. I don't see it much but I'm not surprised by it either.
The whole TED thing is worth a look. Though it frequently indulges liberal pieties it has enough solid, human content to be worth watching. May the people with much money and some sense achieve a surplus of both.
* I'm half thinking about doing a five minute lightning talk on the subject at PyCon. I probably won't but will instead do "PyAsshole: Simulating a partial information, non-trump, drinking game in Python" the simulation of which I've been toying with for a while.
