Why do Jewish young people hate Polish and Poland?

Well, not all Jews hate the Polish. That's like saying all Christians hate Pakistan. However, you didn't say all of them did, so I'll give you the benefit of the doubt that you did not mean all of them but instead those who you know. but if you were getting your info from Jews in Isreal, imagine this: lots of Holocaust survivors went to Isreal (why do you think Isreal became what it was today?) And lots of them had kids, I'm sure. Say when you were six or seven (or older) and you lost your entire family in a concentration camp with Polish Nazis... you aren't such a big fan of the Polish. Sure, that doesn't represent the entire population, just a few bad apples, but if you're a father or a mother and the Poles killed your children, you will never feel the same about them. And the Nazi's weren't the only bad ones, you would often find a Pole betray a close neighbor or close friend who was either Jewish or hiding a Jew. Now, just like pretty much everywhere in Europe at this time, there were thousands of amazing heroes and saints in Poland, but you hold grudges against the bad ones for as long as you live. My great grandmother was deported in her home in Poland and sent to a concentration camp because (she later found out) her neighbors whom she once trusted traded her in. She lost her two brothers and parents but ended up surviving and being liberated by an American soldier who she married and had children with. It's a touching story, but she always says she'll never trust a Christian Pole again (we told her already how that wasn't so politically correct, don't worry.) but I'm sure you'll find many Holocaust survivors are very fond of the Americans because they saved their lives while many Poles did the opposite. (Don't get offended please, I'm Polish and German).
