who tf is this?
They’re a self-described gay, furry ex-mormon who seem to have latched onto the rat & rat-adjacent communities (like EA) in the hope of finding a substitute for the certainty they used to find in religion. Last I heard they work for the Blocked&Reported podcast, i.e. Jesse Singal et al., alongside their job in the US military. (edit: their Twitter claims they’re a law clerk? I guess they moved on.)
On the surface they seem well meaning but naïve, the company they keep (perhaps) being a reflection of that.
TracingWoodgrains is an out-and-out rationalist. Long time poster on /r/slatestarcodex and heavily involved in all things SSC. It just benefits them to be coy about it. Which is whatever! Fine! Who cares? But they’re 100% in the bag for rationalism in any way that matters.
