This hatred mostly exists in American media. In real life there is no more racism in Eastern Europe than anywhere else in the world.
American media, dominated by ethnic and religious groups which historically disliked Poles and Catholics in general, are spreading a lot of bad propaganda about Poland. This is why you have a wrong impression of what is rampant here and what is not rampant here.
Maybe in countries with a lot of Gypsies the situation is different, but these countries are the Balkans + Hungary + Slovakia.
In Poland there are very few Gypsies.
But in opinion polls, Gypsies are still the most disliked ethnic group in Poland (opinion about Black Africans is much better).
Polish Anti-Semitism is not any worse than Anti-Semitism of typical Trump supporters.
So if you think that one exists and the other one doesn't exist, then you are being dishonest.
And I saw some exist polls which show that ~95% of Jewish-Americans voted for Clinton. Compared to ~88% of Afro-Americans.
So it is obvious that every Anti-Semite in your country voted for Trump because they know that "Clinton is in Jewish hands".
Well, if anyone thinks that Donald Trump, with his beloved and trusted Jewish son-in-law, his now Jewish daughter and grandchildren, and all his legion of friends is an anti-Semite then he or she is an idiot. She's not even Reform or Conservative Jewish; she converted to Orthodox Judaism, had a totally kosher wedding and keeps shabbat.

As to your thinly veiled anti-Semitism, be very careful. The Jews didn't mount a conspiracy to defame eastern Europe; you did that yourselves as anyone who has read any history knows, and I'm talking about history as written by historians from many countries, including eastern Europe itself. Every western country has had to re-examine it's own history and acknowledge the horrors it either perpetrated or permitted to be perpetrated. It's time that the former eastern bloc stop living in denial. It's more than time that you yourself do some critical thinking about that too, and stop relying on government textbooks and anti-Semitic tracts dedicated to white-washing that history.
You can spam post after post; it doesn't change what everyone knows to be true.
For your information I know people who voted for Trump and there's not an anti-Semite among them. Some of them are in partnership with Jews, or friends with them, very good friends indeed. Nor would any of them ever join the KKK or read and post on White Nationalist sites, or ever treat a person of color with disrespect, or not hire them for a job for which they're qualified, or forbid their children from going to school with them. School districts are based on neighborhood, which is defined by income level. If you can afford a house in my neighborhood you can send your children to the local public school, as a few black professionals have and do, with absolutely no fuss whatsoever.
You don't know anything about the real America, or the real eastern Europe for that matter, even if you've lived there your whole life. You still believe all the lies, perhaps because the truth is too painful.
