As a Polish citizen living in Poland (unlike Harry and InWrocław who are both foreign ex-pats in Poland) since the moment of his birth (now for over 50+ years), I would not be afraid to advise you to come to live in Poland. I personally know two anti-semite people in Poland in my circle, one is of my family, though not blood-related, and the other is a friend of mine whom I have known since the primary school. The first one is also a driver by profession who regularly goes to Auschwitz with Jewish groups coming from Israel and he says he is generally on very good terms with members of all those groups while driving them to the camp and other places. Their anti-semitism is an economic one which - I believe - they directly inherited from their families. Even if their anti-semitism irritates me enormously, I wouldn't say they would ever offend or insult any Jew(s) when they met them in person even in the very dark part of a town. But they both believe in the "Jewish plot" reigning the world economy and blame the Jewish people as the driving force for the excesses of capitalism. I think it is something that was very common among the older generation of Poles.
The new generation of Poles seems to be completely deaf to all this type of argument. The two daughters of the said member of my family (both 20+) simply mock and deride the opinions of their father every time he tries to play this tune. Anyway, research (the results are occasionally published in "Rzeczpospolita" and obviously in "Gazeta Wyborcza" judged by the local anti-semites to be the "Jewish newspaper" as its chief, Adam Michnik, is Jewish) on anti-semitism in Poland shows its steady decline. You will see, however, anti-semitic inscriptions in Poland or antisemitic shoutings at football matches. On the other hand, I think a Cracovian football club has a Jewish footballer from Israel among them. The former chairman (1992-1996) of the Kneset and also former Israeli ambassador in Poland (2001-2003) Szewach Weiss is frequently present on Polish TV speaking in Polish.
Even if I myself have no Jewish ancestry, I feel in a way part of the Jewish life in pre-1939 Poland. This is becuase my grandpa talked a lot to me as a child about the Jewish people of the southern Masovia village where he lived. He was even taught yiddish by his Jewish friends of the village, but once the rabbi got the news about it, he forbade them to teach him the Jewish language (as my grandpa said, his Jewish friends explained to him that the rabbi did not want the non-Jewish to understand what the Jews of the village say). My grandfather always thought about his Jewish neighbourghs as "people who just live beside us"; I never heard him telling anything anti-semitic, though he was telling me about the common Jewish saying to the Polish in those days that "the street are yours, but the buildings along them are ours", neither was my grandpa filosemitic in any particular way. I am sure many people in pre-war Poland were just like him, but I must say I learned after the death of his brother-in-law that the latter was anti-semitic (and a devoted Communist at the same time, actively fighting the Germans in the Gwardia Ludowa communist underground army). When I went to see Andrzej Wajda's film "Ziemia Obiecana" in the 1970s or 1980s, I suddenly realized that I was looking at the Jewish world I know perfectly well, a world which was nevertheless gone a long time ago.
My grandma left Post-war Poland under Gomułka's lead, and that was due to anti semitism.
If you read in Polish, you should read the book by Teresa Torańska "Jesteśmy. Rozstania '68". This book is precisely about the people who shared the fate of your grandma in 1968. One day I hope to visit Israel to meet some of these people.
