Is this bogus? If you consider theology bogus, then yes. But the paper is highly relevant to current US politics with the influence of evangelical churches and their embrace of a white-centered model of the world. (Although it doesn't explicitly get into politics.)
One irony of linking to this paper is that religion is highly marked by earnestness, and this paper even more so. The paper's author is clearly genuinely interested in this subject as a "theology nerd". She is writing not for personal gain but to make the world a better place.
