Robin Hanson of Overcoming Bias on what it means to be tolerant:

“Tolerance” is a feel-good buzzword in our society, but I fear people have forgotten what it means. Many folks are proud of their “tolerance” for gays, working women, Tibetan monks in cute orange outfits, or blacks sitting at the front of the bus. But what they really mean is that they consider such things to be completely appropriate parts of their society, and are not bothered by them in the slightest. That, however, isn’t “tolerance.”

“Tolerance” is where you tolerate things that actually bother you.
