In its denial of the basis of Western Civilization it is so transgressive that it deserved to be and was persecuted. People who deny there were witches because they don't like how the religious treated them are akin to the Left denying there were Communists because they don't like that Americans reviled them. Jews too were justifiably, though unnecessarily, persecuted for their beliefs and inability to conform to social norms.
There you go.
