Yes, exactly. I don't buy this "contagious" notion. It's simply a change in acceptable behavior. Everyone else is doing this objectionable thing, so suddenly it isn't as objectionable, relatively. It's like looting. If you take any one looter out of the environment, it's unlikely that he would act. But when the crowd of a thousand gets going, well, he doesn't want to be left with nothing while everyone else is gaining. Gotta strike while the iron's hot.
