Mr. Dancona, I think the answer to your question is rooted in American assimilation policies.
Massachusetts passed the first compulsory school laws in 1852. By 1918, all American children were required, by law, to attend at least elementary school.
To achieve national assimilation goals, public school students were subjected to indoctrination, including fake science (aka eugenics, or scientific racism), American mythology (i.e. George Washington and the apple tree) and Christian practices (i.e. Christmas, Easter etc.). Moreover, students were not allowed to write, read, or speak in their own language, practice their own faith and moral traditions, or repeat any un-authorized history, science, literature, religious text, etc. they learned at home.
In this way, and many other ways, white Christians drove their own belief systems, including misogyny, racism, antisemitism, homophobia, and patriarchal, and hierarchical social structures into American culture.
