Nearly all of those statements, emphasize the need for separation of church and state, while our forefathers were not as eloquent as Jesus Christ, they touch upon the same points, the need for the division, and roles that each play.
While this country was founded by protestants, who came here to escape persecution by the murderous "wholely roman empire" which was and is so destructive. Freedom of religion is protected, by our constitution, whole at the same time ensuring that the two are different, and serve their intended purposes without interfering with one another, to the extent that that is humanly possible.
Government, and religion are two separate things. "christian nationalism" is a conflation used pejoratively, like "sovereign-citizen" whereas we all know you cannot be both as sovereign and a citizen... It is possible to be a Christian religiously, and a nationalist politically.
So OP's conclusion, that it is un-American is either a blatant lie, or or an intentional attempt to push a false narrative.
American should all be nationalist, the constitution spells out the duties of citizenship, and the common defense of the union of states is enumerated. Meaning that all citizens must be nationalist, or risk losing that citizenship which is granted to them, and can be revoked. Citizenship is not a right, it is a privilege.
While on the other issue of this thread, Religious freedom, is recognized as a right, and protected by both the constitution, and it's bill of rights, religion can not be revoked.
Our forefathers were well aware of some religious practices that are illegal, such as ritual murders, and cannibalism which was taking place in the Americas, long before Columbus. Those acts were outlawed, and are not protected as "religious expression"
