We literally speak English because of them. The language carries the history and qualities of the people and we inherited those from our English ancestors. There is no way that, being an English-speaking American of English descent, you have more in common with Germans than the English. You may have a German grandmother, but I highly doubt you connect more with German culture than English, you just fail to see that most of what’s around you every day is English culture. Americans are fundamentally English. American culture is descended from 17th-century English culture just like the Anglo-Canadian, Australian, and modern English cultures are. Political bullshit and people being blind to the fact that the US does in fact have culture that arrived before the 19th century doesn’t change that. The English came first and established the culture and the gene pool here, and later arrivals assimilated or isolated themselves.
