My Grandfather fought the "Yellow Peril" in New Guinea and Indonesia and till his dying day would not buy, use, or drive anything "Jap!" For years our elders told him his TV, car, kitchen appliances etc were "made in England " lol
As children we listened attentively to the horror stories and for a time believed that they were still the enemy.
But we grew up. Realised the war was over and that holding on to prejudices and racial beliefs was not how it should be. I liked my Datsun!
When I came to Adelaide 14 years ago, I discovered that there is a large population of German and of German origin people here. In fact a lot of this area was originally settled by Germanic people.
Sadly there is still also an air of racism toward those German people, not directed at anyone personally, but against the German ethos. I guess this happens anywhere...
