Why would you think this is a dark and difficult time in Jewish history with respect to your relationship with Christians?
not today...the time of the crucifixion
Jews have been persecuted over many centuries on continued accusations of Deicide. You cant resolve that by (a)pretending that the original events never happened, (b)one person apologizing and saying the resulting persecutions were wrong, (c) accusing one side or the other of actions that neither has taken in the past, present, or future.
My wife (Jewish) had always been "offended" by the presence of creches in "public" areas. She has since accepted the only real problem was that it was HER problem and accepts that it is not an afront to her (except when she let it be) as much as it is a Christian method of avowing their faith. In and of itself, it places no burden or demands upon her or me.
I perceive "The Passion.." in the same way and would urge thsoe with "problems" to do likewise so we can move forward.
