Anti-Semitism, Missionaries and “Passion” Film

I, as many in the Jewish community, am very concerned about the upcoming Mel Gibson’s “Passion” film. Personally, I’m more concerned about all the talk about stepped-up missionary activity than I am about anti-Semitism that may come as a result of the film. What do you feel should be the response to that issue, and how can we effectively fight it to protect our children and other unsuspecting Jews from that missionary activity?
