Materialist atheists are not of the Right because they do not share the Right's essential motives.
Historically, the Right were defined as those who supported throne and altar against rebellion. They know that Christianity is an essential pillar of all Western nations because only Christianity offers a coherent national origin story that also reinforces each nation's unique identity.
Atomized, hedonistic atheists, on the other hand, at best view the dissident Right as a vehicle to bring them a homogeneous high-trust society where they can indulge in recreational drugs and unfettered crotch worship.
They're barnacles hoping to ride out the storm on Peter's Bark while openly plotting mutiny as soon as they reach the shore.
As for my interlocutor's question, Who cares if Poland, Russia, and China stay Polish, Russian, and Chinese? The answer is Poles, Russians, and the Chinese.
Another reminder appears to be in order. Once again, atheists seeking to hitch themselves to the new Right's wagon have four choices--because late Moderns are all about choice.
1 Confess that Jesus is the Christ and God has raised Him from the dead, and accept Him as your Lord and Savior.
2 LARP for an hour each Sunday at the church of your choice.
3 Shut up.
4 Join the Left. They have all the sexdrugs anyway.
P.S. A few other Twitter users asked me for citations on China going majority Christian by 2050. I originally stumbled upon the prediction while doing research for Combat Frame XSeed. Those notes are on another device which I haven't had time to dig up yet, but another user and I found the following:
First, a 2014 article in the Telegraph titled, "China on Course to Become 'World's Most Christian Nation' within Fifteen Years"
Christian congregations in particular have skyrocketed since churches began reopening when Chairman Mao's death in 1976 signalled the end of the Cultural Revolution.
Less than four decades later, some believe China is now poised to become not just the world's number one economy but also its most numerous Christian nation.
"By my calculations China is destined to become the largest Christian country in the world very soon," said Fenggang Yang, a professor of sociology at Purdue University and author of Religion in China: Survival and Revival under Communist Rule.
"It is going to be less than a generation. Not many people are prepared for this dramatic change."
Next, a report from Pew Research which corrects for under-reporting on the part of China's officially atheist government to indicate that Christians may not be 2% of the population as was thought, but 5%.
