No, he doesn't seem to mind me. He does have his prejudices with regard to America. (The amis is the derogatory German term.)
Two months ago I had lunch with him, another former Wehrmacht soldier and three women from that generation. The other guy was extremely rude. He said many derogatory things about Americans and American prisoner of war camp guards (my dad was such a guard after the war). I don't speak German and didn't know about this until after the dinner when my girlfriend interpreted for me.
I was pissed at her for not letting me know what he said until after he left. She didn't want a scene to be caused. No one in the group said anything to the man or to correct him or to say that he was full of shit. They all kept cheerfully engaged in conversation.
What's amazing to me is that the great crime of that generation was silence. Few spoke out against racist talk. Few stood up against foolish rantings. Sixty years later here was a group of Germans from that generation still afraid to speak up. Still afraid of causing a scene (and my girlfriend too!).
It was absolutely shocking. I was really pissed because my dad had died a few weeks earlier and it was hard to hear this stuff from the likes of these people. No Wehrmacht soldier has the right to call another uncivilized and he did call Americans uncivilized.
The whole thing caused me to reflect a lot. It's something I'll never forget. My girlfriend's generation suffers from what I call "the German guilt thing". Her father's generation doesn't seem to have ever come to grips with what they did.
This is all anecdotal of course. But in my dealings with other Germans it's clear to me that Germans on a whole do think they are better (or their way of life is better) than anyone else. They won't say this anymore but deep down there appears to be an "uber alles" bent.
Other people have different experiences and come to different conclusions than me. This is all just my opinion. I guess the crux of what I'm saying is that it is easy to feel superior and such arrogance isn't limited to Americans. There are lots of examples in the history of the world of such thinking. It's bad whenever it occurs and the worst form of it is to ignore it in your culture while condemning it in other cultures.
