This makes me think of the game theory site linked in an HN comment the other day. I suppose 100% tolerant people would be the naive "always cooperate" players, and 100% intolerant people would be the "always cheat" players.

Interesting to think about how we should behave in this context... If I recall correctly, the ideal behavior would be the copy-cat?

This seems to validate the 'intolerant of intolerance' objective.
