"I wouldn't call it a Christian tradition. Roman or Gentile perhaps, but watch "The Passion" and discern which party is promoting the mockery and killing of Jews."
If you really are completely unaware of 2000 years of continuous Christian persecution (a persecution often promoted by the kind of blind bigotry displayed in your post) I would suggest that you take a trip back to high school.
Our Lord and Savior Christ Jesus, who is King of the Jews and the King of Kings will return during a second Advent which will be even more spectacular than anything in the last 2000 years. Vengeance is His. Today we live in an age of grace.
He is here for the Jew first, and Gentile second. The true Jews as God created them, follow Him faithfully as their their true Jewish faith was given them. Those counterfeit Jews who reject Him merely provide an eternal memorial in heaven of their foolish rejection.
It's incredibly difficult to observe a body of people falsely accuse somebody, beat him up, force him to carry a cross for mile, crucify Him, and then claim they were the ones being persecuted. Such are the ways of a 'unbigoted' worldly system of good and order independent of faith in Him. /sarcasm off
