Some people didn't quite like the position I staked out that more vegans and animal advocates should subject carnists to conversational intolerance. I was told, in both comments and through some private communications, that it was counterproductive.
Well, here's one account of a situation where it actually worked. I'd never presume to universalize this evidence, but I think it speaks for itself. Sometimes the cold shoulder and the scornful gaze are more effective than any amount of fact-slinging or heart-tugging. It depends on the circumstances, of course. Still, there's more than one way to peel a banana.
