I love ideas, data, speculation, experiments, and plans.
I also love arguments, refutations, and attempts at persuasion.
And I think what I love the most about the United States is the general legal consensus that outside of inciting people to acts of terrorism, one is allowed to say what they wish without government censure. In this sense, I am and have always been a free-speech absolutist. If somebody wants to make the case that a grave sin is actually sane and good, I’ll hear it. If somebody wants to claim that mega civilizations can control galaxies for energy and call it science, I’ll listen to Michio Kaku:
But, how free speechy (I think I made that up) are we?
Paul Graham suggests a test for your own free speech absolutism by positing a test for moral fashions:
What scares me is that there are moral fashions too. They’re just as arbitrary, and just as invisible to most people. But they’re much more dangerous. Fashion is mistaken for good design; moral fashion is mistaken for good. Dressing oddly gets you laughed at. Violating moral fashions can get you fired, ostracized, imprisoned, or even killed.
If you could travel back in a time machine, one thing would be true no matter where you went: you’d have to watch what you said. Opinions we consider harmless could have gotten you in big trouble. I’ve already said at least one thing that would have gotten me in big trouble in most of Europe in the seventeenth century, and did get Galileo in big trouble when he said it—that the earth moves. 
It seems to be a constant throughout history: In every period, people believed things that were just ridiculous, and believed them so strongly that you would have gotten in terrible trouble for saying otherwise.
Is our time any different? To anyone who has read any amount of history, the answer is almost certainly no. It would be a remarkable coincidence if ours were the first era to get everything just right.
It’s tantalizing to think we believe things that people in the future will find ridiculous. What would someone coming back to visit us in a time machine have to be careful not to say? That’s what I want to study here. But I want to do more than just shock everyone with the heresy du jour. I want to find general recipes for discovering what you can’t say, in any era.
This particular test is useful. Are my ethical standards determined by the cultural fads or careful reasoning? Christians have a tendency to feel that the Holy Spirit and deep study have prompted them toward some new ethical insight that really is just a way for them to stop being at odds with the dominant culture (sad). But my version is this:
Could you listen to the views of somebody from any time period or culture, insofar as they are not inciting terroristic or mob violence, and not want them silence, jailed, or executed?
Obviously, this is context specific. Church services aren’t the place for giving heretics a voice, children’s classrooms aren’t the place for letting philosophical cases for sexual deviance be made, and so-on. But I think this test for free-speech absolutism is key. Am I, then, a free-speech absolutist?
