It comes across to me that there's a lot of culture warring in it that's irrelevant to the task of actually figuring out what's true. Bringing up Damore and "sealioning" within a few paragraphs is more than enough to establish for me that this is not about trying to have any kind of constructive discussion.

Aside from that, it's curious how I've been interested in these ideas (and following SSC) for like a decade and this is the first I've heard of the castle. But I do hear about the Against Malaria Foundation constantly from that direction, and I'm pretty sure they've received more than 15 million from self-styled "aspiring rationalists" and "effective altruists" (although these really aren't meant as identity labels and you're doing it wrong if you think of yourself that way; pg's "Keep your identity small" represents solid rationalist thinking).
