Antisemitism is unique among religious hatreds. It is a racist conspiracy theory fashioned for the needs of messianic and brutal rulers, as dictators from the Tsars to the Islamists via the Nazis have shown. Many other alleged religious 'hatreds' are not hatreds in the true sense. If I criticise Islamic, Orthodox Jewish or Catholic attitudes towards women, for instance, and I'm accused of being a bigot, I shrug and say it is not bigoted to oppose bigotry.
