>>115291350For a real answer, the reason has two related answers. They dislike traditional Jews because they do not accept that Jesus was the prophesied Messiah, seeing him at best as nonexistent, and at worst as a heretical false prophet. There have been charges by medieval Rabbis that Jesus was, in fact, a practitioner of black magic, and other side have been the accusations of blood libel against Jews. Make of that what you will.
The reason why many eschatologically minded Evangelical Christians want Jews DEAD is because, in their theology, once every Jew on Earth is simultaneously dead, it will bring about Armageddon which will herald the Rapture and the return of Jesus.
Personally? There is no evidence of any god or gods, so I have no reason to behave as if there is one.
