I have posted before about anti-Semitism in the Swedish city of Malmo. There is a report here (also here) about a solidarity march with Malmo's Jews: a 'kipah walk'. It isn't possible to tell from the report how many non-Jews have been involved in it, but at any event it was both Jews and non-Jews. It would be good to see more of this kind of thing in face of current anti-Semitism.
