It's really hard I think. I am not Jewish but I am Pro Israel and Pro Jewish! People hate me because I like Jews and Israel. I hadn't any trouble at work. I always wear the Magen David. You can see a pic of it in the topic "Ask Chaim Ben Pesach the hero". It's a golden necklet with a golden Magen David. I always wear it because I think it protects me and it gives me power. So my boss didn't said anything against it. I know he recognize that I wear it. But he didn't said anything. But at school (Berufsschule / trade school), there are a lot of people who would kill me because of it. There are so many muslims (turks, arabs, lebanese,...) who are against Jews and Israel. If there will be one dirty muslim who say anything against Jews or Israel then I will go to a teacher and tell him that the person is antisemitic.
