Mr Levy, you present it as we did not know before. It is all about ignorance due to the fact that a lot of jews including israeli jews are closed up in their own world out of contact of other cultures. So when we see smb from a different culture/color even if he is jewish, he is subject of rejection. I have seen it many time in the diaspora and in Israel. The solution has a name and it is called "Education".
