That European Jews are European does not make them less real. Christianity began in the Middle East too, and European Christians are very real. They're just not entitled to steal land in the Middle East.

Yiddish is about 80% German, and it includes words that don't come from Hebrew.

Americans never deny the lands that they come from. They tend to be proud of them, so we talk about Polish-Americans, for example, yet no one talks about Polish-Israelis, in part because Polish-Israelis tend to have changed their names to something that sounds less European.
