I have never heard the American media refer to Polish Americans as "American polaks". Honest to God.... NEVER
...and you never will. Chicago P is smoking crack. The term used in the media is Polish Americans and that is the only term you'll ever see. The word Polack is considered derogatory, sort of like the N word and the media will never use it. Ironically, it's become a derogatory term because of Polish American's complaints over the use of the word Polack.
USA is the most segregated country in the world. White hating black, blacks hating whites, whites hating jews in the south, then italians polish mexicans english puerto ricans etc etc hating each other.
Have you actually been to the US? Granted, racism exists here and everywhere else too for that matter but this "hating" you're talking about is perpetrated by a tiny minority of people and often highlighted by foreigners who despise america for different reasons and want to believe this nonsensical garbage just so they can feel better about themselves. Look in the mirror princess.
Amazing that a Russian who's writing on a Polish forum has opinions on racism in America. Russia, the country whose citizens throughout many centuries have murdered more people on earth than any other nation ever even "dreamed" of, wow.
