In the U.S., this drive to preserve white Christian dominance undergirded the worldview of the Ku Klux Klan when it reemerged in the early part of the 20th century. We rightly remember the terrorism aimed at Black Americans, but the KKK was also explicitly anti-Jewish and anti-Catholic; it existed to protect the dominance of a white Anglo-Saxon Protestant America.
Why are we seeing the rise in white supremacist violence over the last decade? In short, in the U.S. context, the election, and re-election, of our first Black President coincided with the sea change of no longer being a majority white Christian nation (as I noted in my book The End of White Christian America, white Christians went from 54% to 47% in that period, down to 44% today). These twin shocks to centuries of white Christian dominance set the stage for Donald Trump.
Trump’s “Make American Great Again” formula—the stoking of anti-immigrant, anti-Muslim, and anti-Black sentiment while making nativist appeals to the Christian right—contains all the tropes of the old replacement theory. The nostalgic appeal of “again” harkens back to a 1950s America, when white Christian churches were full and white Christians comprised a supermajority of the U.S. population; a period when we added “under God” to the pledge of allegiance and “In God We Trust” to our currency.
These fears about the “great replacement” are not fringe among conservative subgroups today, according to recent data from PRRI. While only 29% of Americans agree, for example, that “Immigrants are invading our country and replacing our cultural and ethnic background,” that number rises to dangerous levels among a range of groups comprising the conservative base in U.S. politics: 67% among those who say they most trust Fox News; 65% among QAnon believers; 60% among Republicans; 50% among white evangelical Protestants, and 43% among white American without a college degree.
The clear historical record, and contemporary attitudinal data, merit an urgent discussion of white Christian nationalism as a serious and growing threat to our democracy. if we are to understand the danger in which we find ourselves today, we will have to be able to use the words white Christian nationalism and domestic terrorism in the same sentence.
