Ethnicity is about culture. Not DNA.
There is ethnicity AND there is culture!
Your DNA might point you to germanic, slavic or celtic ethnicity (often a mix) and you might grow up still with the culture of a Pole or a German or whatever.
Is Poland in it's majority formed culturally or ethnically by Jews?
Nope...hence no jewish roots of Poland.
Jewish cultural influence? Of course!
Were there influential Jews in Germany? For sure...has Germany jewish roots, nope here either.
Where there Jews who assimilated and left their jewish heritage behind to adapt to german or polish culture, you bet!

The typical exception who proves the rule.
You wouldn't bring him if he wouldn't be so rare in Germany and you know it! ;)

"For too long we've been used to the fact that we have primary school classes in which 80 percent of the children don't understand German," he said.
