It was inevitable that X would become a vector of race pseudoscience.
Some people like to imagine that Musk was radicalized by the existing racist content on Twitter/X. But Musk and his PayPal pal Peter Thiel have been racists for a long time - probably their entire lives considering that Musk comes from South Africa and Thiel comes from hyper-Christian German immigrants who became "fanatical Republicans" and, like Musk, grew up in South Africa during apartheid.
But they even brought their racist beliefs into the workplace, as discussed in "Contrarian" the book about Thiel by Max Chafkin. Thiel was a founder of the now-defunct Clarium Capital, and Musk was an investor (my emphasis):
Clarium employees read, played chess, and debated (sample topic: If you were going to design a country from scratch, what would it look like?) Everyone spent a lot of time talking politics, though it was important that those politics always be of the right-wing variety. An employee told me that it was common to hear talk about climate change denial and to see web browsers open to VDARE, the far-right website with a long record of publishing white nationalist writing. There were liberals at Clarium, but they understood that it was best to keep those views quiet.
VDARE, which also seems to be defunct now - hooray - is about the most racist organization this side of American Renaissance. VDARE was infamous recently for buying a castle in West Virginia.
But is VDARE really necessary for white supremacists now?
After all, Elon Musk, stochastic terrorist, white supremacist, anti-Semite, misogynist and best buddy of fascist Trump, possessor of many US government contracts and beneficiary of billions in US government subsidies, and all around horrible human being, now owns America.
