I take offense at that.
Since you obviously don't know anything about Jews, let me tell you some things.
We only give a shit about Jesus to the extent that his "followers" fuck with us. That, historically, has been quite a bit.
So if a movie has any hint of anti-semitism, Jews get a little anxious because we're so aware of past and present religious persecution. Even to this day Jews die by the dozens due to suicide bombings in Israel. So excuse our attitude, which is one of, "Just fucking great, another group that sees us as the Enemy."
What makes this movie so bad is that it has the potential to incite anti-semitism in a group that, so far, has largely left us alone: the modern american christian.
Does that make sense?
