Silviu has an awesome post linking to a paper that actually quantifies the hatred and that suggests a model in which politicians with resources and incentives to supply hate-creating stories interact with people who may lack the incentives to properly question these stories. In this model politicians differ in their income distribution policies and can spread hate-creating stories about the dangerous character of a minority group. Voters who hear these stories think they might be true, but only choose to invgestigate those stories if there are private benefits from learning the truth.
Actually this is to some certain extent what had happened in Romania at least 10 years after 1989, when Ceausescu was shot and the neo-communists took the power. Stories like the danger of Hungarian minority, the rumours and would-be threats about the punks (golani) from the University square, the miners riots and the way they were manipulated for so many times, the strikes, the unions, the "we don't sell out country" slogans, or the BCR threat-to-crash are just a few stories that come now into my mind. Actually Romanians have a saying: speak as badly as possible about a person, there will always be some stains remaining.
Now my impression is that things tend to fade away, and Romanians are not as easy to be fooled. We will see in Novemeber.
