I am a swedish jew from a family that fled from Germany to Sweden in 1939. You are right in that Sweden was late in granting jews the right to live in the country (1700's) Not last though. However, your description is flawed. For instance, the law you referr to that was taken away in 1951 was never enforced after around 1850. There are lots of strange old laws in many countries that are just old remnants and not enforced (check in other countries as well). Also, in contrast to many other european countries, Sweden has NEVER persecuted jews. Jews have always been able to live in the country in peace and there has been no need to "hide". Oh, and no, Swedes, do not look down on fins, norwegians or danes (or anyone else). Don't mistake the friendly bantering between neighbours as something else.
