Uh uh.... I don't find the slaughter of my fellow Jews all that funny.
Finally, face facts that Jews were a mobile, rich group of people who could have left (and DID leave) persecuting nations (as they did from France, England, Spain) -- and yet they came and stayed in Poland and PROSPERED. They called Poland "Polan" -- the blessed land.
Why did they stay? Because the stories of them being persecuted are just that, stories.
When the Tsarist pogroms happened in the 19th century, that started a wave of migrations to the USA. Why would they have stayed if the Poles were persecuting them over such a long period?
