First, what facts do I know.
There was no prosecution of Jews in Finland
Jewish POWs were separated in special POW camps for Jews. They were told that Finnish people hate them and they are to be transferred to Germany. But the intent changed and only Communists were actually transferred to Gestapo. Other Jews were allowed to contact with representatives of Finnish Jewish community.
Finnish authorities installed special ethnic-cleansing conentration camps for Slavic-speaking inhabitants of Karelia and other occupied territories.
I wonder whether the Jewish civilians were threated separately of Slavic population.
