Ah, the Jews should "share" some responsibility in the hatred Jews by so many Poles.
Why did the Jews "choose" to live in Poland? For the same reason they "chose" to live in almost every country in the world after they were led in chains from the Holy Land.
The Jews *did* choose to live in Poland in large numbers, because Poland (before it was divided and taken over in the 18th C) was more tolerant toward Jews than were most other European nations.
