The Future of Social Norms

Paul Graham sparked a fascinating debate here on fashion and morals. What are we saying and doing today that one day will seem unfathomably bigoted and immoral? Hal Finney ran with the ball here. Ilya Somin thinks the death penalty will one day look like barbarism. Manifest Destiny takes a different approach and asks what immorality will one day look like. Money quote:

"My money's on voluntary limb amputation."

Tim Lee figures his libertarianism is biasing him. It's an interesting topic. My own candidates for what we find morally ok today that we won't in the future are: abortion-on-demand, factory farming, and discrimination against gays. But my biases may be showing too.
