As I mentioned in a sibling comment, the contention I intend to make is that he agrees more with the racial views of his NRx commenters than he publicly let on. That was the framing of the NYT article -- nobody thinks or would be incensed to learn that SA is a Neo-Monarchist or any of the other NRx beliefs that are orthogonal to modern US political discourse.
If you don't think racial IQ disparities are a significant part of NRx thought, fine, you're probably better positioned to know and I am happy to concede the point. In that case, a better comparison would be to Steve Sailor's views. I only mentioned NRx because that is the context of his emails, and I had not recognized that he was linking to Steve Sailor's blog.
