Well for once I think I translated correctly I was just acting as a "Poil à gratter"* as we say here 

To answer (preety incompletly) to your question 
Why do the Jews seem to be the most persecuted people in history?
 Note : I'm excluding the industrial tragedy made by the German in this reasoning.
I don't think it can compare to the pogrom and diverse  persecution the Jew had to endure during the ages to this.
I don't know exactly why they look to be more persecuted.
It's perhaps because their civilisation/religion survived during a long time when other just vanished and we don't even remember of them ?
Example the maya civilisation didn't survive and none care of them.
@lasersailor184 : you are speaking of actual of historic Europe ?
