I think that every time a Jewish group says this should not be released, a new anti-semite is born in the world. I'm not sure The Passion will work as effectively, although I haven't seen it - so maybe their worrying is justified.
Anyways, now that Jews have Israel, they shouldn't be so worried about anti-semitism. They can move there and be safe.
My family did that, and look how well I turned out
