Unfortunately, a lot of people thing that, if they think something is bad, they must do something about it. And they consider tolerance to be giving in to badness.

Precisely the attitude that needs to be changed. If you can get people to believe that it's okay to not interfere with something they perceive as bad, you don't have to get them to believe that it's not bad -- just that it's not their business.

In other words, all that is really necessary for the triumph of Not Actually Evil is for the self-righteous to do nothing.

...*eyes self* Okay, that was unsettling.
