jews returning to their town were murdered by their former neighbors. And it's known that this happened in quite a few places.
As much as it is incomprehensible to me and utterly terrifying, I'm afraid that such
events did, in fact, take place after the war (although they weren't as common as
some biased historians would have us believe).
I'm quite sure that 95% of so called "anti-semitism" in Poland is simply fear
of those who stole Jewish property or even claimed it after the war out of
necessity without any malice or bad will. They fear that the rightful owners
might come back one day and ask for what's theirs.
The right to one's property is a mainstay of western civilization and should
never be undermined or denied to anyone. The rightful owners or their lawful
descendants should get all their property back.
Of course, by that, I mean individual people, who can prove the right to a given
property and not some chutzpah organisations, operated by a bunch of con-men
who have nothing to do with rightful owners of Jewish property in Poland (apart
from, maybe, their nationality).
