I'll let another JTF-er write the Jewish perspective about Horowitz. From what this Gentile knows, Horowitz was once a hard leftist, but came to be repulsed by the behavior of his leftist colleagues His transition took years, and Horowitz grew to become a campaigner against 'political correctness' (I prefer the words 'cultural marxism') on college campuses. Given that the last college PC fad is this bizarre sympathy for Islam (a force that has no sympathy for feminism, gays, etc), it would be my guess that Horowitz has started to confront PC sympathy for Islam also.
