According to Western standards. You judge them by standards of other culture. This is racists.
I stressed "liberal, cultured, from Warsaw" for a reason, and they are mostly more knowledgeable about the world than I am. They DO know what they're saying, and aware that their casual terminology carries with it incredibly hateful connotation, they just don't seem to care. I don't often discuss topics of racism with the average Pole, so I don't know about general attitudes. I simply note that some of the most intelligent, liberal and worldly people I've ever known that are from Poland have no issues with being racist.
Seriously though - I don't pretend that we are innocent island of tolerance in the racist world. I simply state that even developing racism takes time. We never got that time.
Maybe in 20 years we become a racist nation - who knows?
Racism is not an acquired viewpoint, it is quite primitive and natural, hence why it is so common. Poland may not have racial stereotypes yet, but it's perfectly possible for someone to hold prejudices based on race.
