commonsense:
Thousands of Jews returned in 1945, many were driven away and murdered and those that were stupid enough to stay were expelled in 1968.
It might be good to check the ethnic composition of the "Polish" government after WW2, especially UB (polish KGB). That may give you hints as to why some behaved the way they did.
commonsense:
Rememeber, I'm not stupid, so don't insult my intelligence and blame the Nazis. Like my name on this site, common sense is a man's (and a woman's) greatest weapon.
We can't forget that you are not stupid because you haven't let us see your wisdom yet.
As for the common sense, you show off the weapon but you have no clue how to use it, ergo you are just another low end yapper.
