Thanks for posting. My great grandparents moved from Cologne to Danzig in the 1890s. My grandfather fought for the Germans in WW I, was captured by the Russians, escaped and walked back to Germany. Nine years after WW I ended, with the civil breakdown and hyperinflation in Germany, he packed up and took his young family to the US. My Dad was three when they arrived. He told me a lot of tales of living in tenements in NY CIty, how he had to fight all the time for some years because he was German. The hatred started in WW I took a long time to subside.
I'm a WWII baby, and while I don't HATE 'em, they're still Japs and Krauts or Nazis to me. And the French are still Cheese Eating Surrender Monkeys.
It has never subsided!!
