It does not matter. In many European countries you can go to jail for asking questions about jews. I used to work as an architectural design software specialist and traveled for conferences and training all over Europe. I have often used as a joke that something is made of Saudi passports and I have watched the people and their reaction to it usually they were structural engineers and architects. Some were initially confused with conformism but superficially, and after making sure they could express their thoughts safely, I didn't meet a single person who would believe the official version of the events except for one professor in college but he was the head of Rotary club for several countries and did the famous masonic handshake to me.
