It is also reported that millions of non-Jews also died in the death camps - freedom fighters, Catholics, gays, artists, etc. But be careful where you look for your information about that because there are many white supremists who like to exploit and twist that kind of information.
Although I see your point, I think that Susan (Soosan) and her hosts were just poking a little harmless fun at each other, and laughing about the absurdities of stereotypes. (Please Susan, correct me if I'm wrong.) I got the impression, especially after Susan's response to my smoking post, that nothing was meant as a serious overarching statements about American v.s. Germans.
However, it does seem to me that the persistance of racism in both Germany and America is one way in which both countries *are* alike.
