In a review of Geoffrey Beattie's Our Racist Heart? An Exploration of Unconscious Prejudice in Everyday Life, Eona Bell says:
The key argument [of the book] is that, regardless of the liberal and open-minded attitudes we may consciously hold, we all have unconscious biases which can lead to prejudice in our interaction with other people.
You might think this a well-known thesis, and you'd be right to. But it is the very thesis that is forgotten or implicitly denied - often when there are Jews involved – by those who claim that what they say or write or draw can't be racist because their intentions aren't. Two thousand years of prejudice such people just know to be over and done with. Unconscious biases, themes and symbols linked with traditions of hatred and persecution, these are then, strangely, as nothing.
