One's upbringing has a lot to do with one's perspective. No matter how much you love your adopted country, you will always have a German inside you, too.
One of my grandfathers was German and immigrated here as a young man. But about the only heritage left in me is pigheadedness and love of sauerkraut. And I remain in a Lutheran congregation, whereas my brother proudly claims the English side of his heritage and declares himself an Orthodox Druid if anyone asks.
