As Christians, we shouldn't hate anyone.
However, we have to realize that there is an anti-Jewish sentiment within our faith. Why? The Jews are the first heretics. Heirs to the promise that rejected the True Faith (that is, obviously, faith in Christ). They crucified him. However, we cannot blame today's Jews for their blasphemy any more than I could be blamed for the Spanish Inquisition.
At the same time, Jews (as a people) have separated themselves from the People of God, now revealed in the Church. I'm personally not a fan of interfaith dialogue. I don't really see the point. All Jews are free and welcome to join the Church and participate fully in Her mystical life. Areligious Jews (the majority today, it seems) might as well be counted simply as atheists, and religious Jews counted as heretics and simply ignored. They have nothing to do with the life of the Church.
Now, Zionists are quite meddling and dangerous. They are religious zealots, but again...that has nothing to do with the Church. Crazy religious Jews or sane religious Jews, they are a withered olive branch, until they decide to be grafted back in. No reason really to talk about them at all, and especially cause such scandal, though I don't generally approve of meeting with Jews for "dialogue" (or Muslims, Hindus, Buddhists, Taoists, etc.), Bishop Williamson needs to keep his mouth shut.
