No, I don't. Assimilation goes with immigration. I immigrated and assimilated.
If I asked my US-born daughters if they are assimilated, they would say: Hey, dad, what the hell is the matter with you? Are you drunk?
All those who were born in Poland had no damn reason to "assimilate". If they are not assimilated having been born in Poland, they should expelled from Poland.
It's that simple. That's why I can't stand Amish.
