I'm on the left. I think Urbit is quite neat as a technology. Yarvin has very unusual political views, so I'm not sure where to put them, or if you'd consider this "sound-bite mudslinging" (if you do, please suggest a more palatable way of providing evidence:)
He seems pro-monarchy:
Was royalism a perfect system? It was not. But if we imagine a world in which the revolutions and civil wars of the last four centuries had never happened, it is hard not to imagine that world as happier, wealthier, freer, more civilized, and more pleasant.[29]
but anti-democracy:
When we look at the astounding violence of the democratic era, it strikes me as quite defensible to simply write off the whole idea as a disaster, and focus on correcting the many faults of monarchism:
He seems to regard political power as property, which makes a sort of sense with his monarchism:
Political power is a property right, however you slice it. It is owned, not deserved. It is not a natural or "human" right. And it has no more to do with freedom than brake fluid with fondue.[40]
Here is yet another (idea for good government): restrict voting to homeowners. Note that this was widely practiced in Anglo-American history, and for very good reason.[41]*
(He also favors property ownership as a requirement for voting, which aligns with Urbit's governance but seems... dated, politically.)
And he seems to view slavery as a potentially healthy relationship:
Modern Americans have enormous difficulty in grasping hierarchical social structures. We grew up steeped in "applied Christianity" pretty much the way the Hitler Youth grew up steeped in Hitler. The suggesting that slavery could ever be or have been, as Aristotle suggests, natural and healthy, is like suggesting to the Hitler Youth that it might be cool to make some Jewish friends… We think of the master-slave relationship as usually sick and twisted, and invariably adversarial. Parent-child relationships can be all three. But they are not normally so. If history (not to mention evolutionary biology) proves anything, it proves that humans fit into dominance-submission structures almost as easily as they fit into the nuclear family
It's hard to classify Yarvin anywhere politically, but given some very extreme views on slavery, democracy and dictatorship, I think "far right" is as accurate a label as any. His views are expounded upon in the Dark Enlightenment article in the summary.
