My Polish/Russian wife grew up in a heavily ethnic, Eastern European neighborhood in Toronto,....mostly Polish, but also Russian Ukrainian, Moldovan, ect.
Anybody there who was Ukranian kept it to themselves. There was plenty of good people there with Ukranian heritage. But they arrive with the knowledge that it wasn't a good thing to advertise it. They never got over that way of thinking.
All those euro-trash fugks keep their lineage to themselves when it's convenient.
That's what makes them euro-trash.
