That's the point..."historical fact." "Christians," I would hope, are not as narrow-minded as they once were in in thinking that Jews were totally responsible for the crucifixion of Jesus Christ. They were instruments, but not the cause. We are ALL the cause. As mentioned earlier: It was my hand on the hammer and my sin on His shoulders.
Foxman doesn't get it. Maybe he's just afraid Jews will go to the movie & get converted. Doubt it, but it's possible.
No, he is afraid they will come up all pumped up with anger against Jews (mainly overseas and not in America). It has happened before for centuries. He is paranoid that the "blood libel" will be used again, but there is a historical basis for his paranoia. Human nature did not change in the 20th Century. What makes you think it will change in the 21st Century ?
