I'm interested and willing to engage in such discussion. If you are too I'd ask you to perhaps make a list of the posts you have read so far? For now I'm assuming you began with one of the recommended essays like Idealism Is Not Great, Divine-right monarchy for the modern secular intellectual, Formalist Manifsto. Perhaps the introductory Open Letter to Open Minded Progressives or the Gentle Introduction sequences.
To this I would add the comment history of fellow LWer Vladimir_M which is littered with high quality Moldbug-like arguments on various issues. Who knows a few new responses might coax him out of inactivity!
I recall some old sort of interesting discussion of Moldbuggian positions in which I participated as well:
Thanks thats a helpful summary.
Slightly related question, why are his views seemingly being suddenly discussed a lot and taken semi-seriously on LessWrong?
