The descendants of German Protestants in the USA are going to be so heavily intermarried with WASPs and in the Upper Midwest with Scandinavians, and are just such a milquetoast ethnicity, as to be almost unspottable even though actually one of the largest population groups in the US. They have no cohesion as a group.
WWII did a lot to kill German qua German identity in the US. After the films came out about the death camps, German bars, and so forth closed, so said a client of mine who was of German ancestry from Milwaukee. Many he said in his conservative Germanic circles in Wisconsin, were rather pro Hitler behind closed doors, until it was impossible to deny the horrific genocide, and that something in German culture itself needed needed to be seriously pondered. It is unimaginable to me, that even early in the Hitler years, when he was shooting folks right and left who were political opponents, and bragging about it, the German establishment appreciated the ends of a more "orderly" society, rather than the means of a total abandonment of the rule of law, in favor of the rule of a madman. I just can't imagine that would have happened in a common law Anglosphere nation. Maybe I am naive.
But long after one loses a sense of ethnicity, or jettisons it in the manner described above, the attitudes carry on without an ethnic label. Attitudes have long half lives.
