I don't see why you find it offensive, since it is more a historic comment, made by a Jew, who for whatever reason converted to the Anglican Church. It isn't meant as a "statement of fact", but tells us more about Disraeili, than anything else. There are a lot of offensive, or just silly quotes on this site. I just solve them, and move on. I say that as one whose mother's family was Jewish. If I thought about it, I would be offended by various "atheist" qoutes on this site. But I am not getting my theology, nor my philosophical education here, just entertaining myself. There have been some offensive quotes about the Catholic Church, and Christianity in general, here. So what? I just solve them and move to the next one.
