Look, I know I sound glib here, and I'm trying not to be, I promise I am, but the funniest part about this is:
(1) I agree, Alexander isn't a supporter of neoreaction-ism, and
(2) One of the few valuable bits of information he claims to have gleaned from them is NRx-flavored HBD!
You get how that's essentially saying "well, I definitely don't think we should create a global monarchy, but those people do seem to have a point about the suitability of Africans for chattel slavery", right? That's what NRx-flavored HBD is. (I mean: it's really what all HBD is, but the NRx people are explicit about it.)
But don't just take my word for it. One of the two "more" well-supported links he cites is to Steve Sailer's blog!
I am not here to call you a racial supremacist for enjoying Alexander's writing, for whatever that's worth to you. I like a lot of Christopher Hitchens writing. That doesn't make me, personally, an alcoholic.
(I edited this a bunch, but tried not to change the meaning of anything I wrote previously. Sorry if that was annoying.)
