This was an excellent read if you're aware of the emails but never bothered to read his citations or to dig into what the blather about object-level and meta-level problems was specifically about, which is presumably most people.
So, a deeper examination of the email paints 2014 Siskind as a pretty run of the mill race realist who's really into black genes are dumber, you guys studies and who thinks that higher education institutions not taking them seriously means they are deeply broken and untrustworthy, especially with anything to do with pushing back against racism and sexism. Oh, and he is also very worried that immigration may destroy the West, or at least he gently urges you to get up to speed with articles coincidentally pushing that angle, and draw your own conclusions based on pure reason.
Also it seems that in private he takes seriously stuff he has already debunked in public, which makes it basically impossible to ever take anything he writes in good faith.


Honestly what he should actually be grateful for is how all his notoriety ever amounted to^[1]^ was a couple of obscure forums going 'look at this dumb asshole' and moving on.
He is an insecure and toxic serial overreactor with shit opinions and a huge unpopular-young-nerd chip on his shoulder, and who comes off as being one mildly concerted troll effort away from a psych ward at all times. And probably not even that, judging from Graham Linehan's life trajectory.
