I hope you are right.
However, my point was as far as I'm aware, the church generally did not have any objection to mixed-race marriages except in very particular times. I'm certain the Anglicans, the Catholics and the Orthodox, historically the biggest groups, had simply nothing to say on the matter. This is despite multi-ethnic states and cities existing throughout history.
Whatever theological justifications were put up in north America wouldn't have much historical validity.
