Jews and Europeans have been in contact for over 2,000 years, which is more than enough time for ethnic hatreds to develop on both sides. Obviously.
Please, don't try to weasel your way out of this one. You've already tilted your hand. You claimed that an Israeli
Jew is prone to knee-jerk ethnic hatred of Europeans. In case you don't own a map, Israel isn't in Europe. It's in the Middle East. If you actually knew anything about Israeli people, you would notice their ethnic hatreds lie pretty squarely on...surprise, surprise, Palestinians and other neighboring Arabs.
Promoting racial / ethnic separation is fine. Opposing the propagation of Jewish values among your own people is fine. Making legitimate criticisms of Jewish people and culture is fine, as is the pointing out of genuine grievances. Making shit up about Jews isn't. I'm not a member of the ACLU or Anti-Defamation League, so I'm not going to press any further. However, you did make a strikingly ignorant comment about Jews.
Oh, god damn it. You know I have to eat your first born son now, right?
