I believe Malmo is the worst European city in this regard. Muslims do play a large part in it, together with the left. Although I donot hear much about it I am sure the extreme right also plays it part. The left not only plays an active part, but also an important more passive part by 'reasoning' away violent antisemtism with the perceived policies of Israel.
In many European cities, jews donot dare to walk with their kippah anymore.
That said, we shouldnt forget that some time ago there was the following comment in Haaretz:
aliyah from sweden not due to antisemtism
dennis 12.07.1018:01
I am a Jew from Malmo who made aliyah 4 years ago. I am well acquainted with the situation in Malmo and although there is a serious problem with anti-Israel sentiments in the city, the above description is grossly exaggerated. My parents and several of mine and their friends still live in Malmo and can also attest to that. I know most of the other Jews who made aliyah from Malmo and almost none of us made aliyah because of anti-semitism, but rather because of a dying Jewish community and a lack of oppurtunity to retain our and our children's Jewish identity in the future. The aliyah from Malmo is a matter to rejoice over, not to mourn, since it fulfills the generations long yearning for a return to Israel and guarantees the continued Jewish identity of the Malmo Jews who made this brave decision.
