Germans treated jews with more decency than anyone in the history of Europe (with the exceptions of *maybe* the judeophile French and stingy Dutch). And look where it got them.
Depending on the timeframe intended here (quote does not specify) this could be legit. Germany was known as something of a safe haven for jews for centuries which is why so many German-ish sounding names are synonymous with kikes and why and how Weimar got as bad as it did.
