Earlier quoted context omitted.
Its the whole of collections of views he is public about. We talk a great deal of "Good Fit" and the like when working on projects with others, or working for someone. This is a case where he would work better with his own kind: racists, sexists, and bigots. Like attracts like.
You mean aside from the project under discussion? Why are his personal views even relevant here?
If you look at Bitcoin and the blockchain as a purely technical achievement, it's marvelous and incredible, a testament to human ingenuity. The problem is that money is not a purely technical problem, and people involved in Bitcoin who ignore that open themselves to a whole lot of relearning, like when people who are given the ability to steal a whole lot of money end up stealing a whole lot of money, like at ShapeShift[1]. Banks have been dealing with these kinds of problems for decades (or, depending on how you look at it, hundreds if not thousands of years). But if you only concern yourself with the technical aspects of Bitcoin, not the social or political aspects, you can miss things that seem obvious with the benefit of hindsight.
And the software that people creates has implications that range far beyond technical questions. A great example of how we can encode assumptions that come from our beliefs, our experiences, who we are and where we happened to be born into software without even realizing that we've done so is the fantastic essay "Falsehoods Programmers Believe About Names[2]." Reading that should be a real eye-opener about how, without intending to, programmers can end up writing software that is built for people Like Them and is unaccomodating to people who Aren't Like Them.
Most of the talk about his personal views here are about his views on race. It shouldn't be a huge surprise to anyone that the sort of people who are at Hacker News are likely more white than the rest of America, much less the world. As are a lot of the people writing software in use today. Sometimes that means that Google Photos categorizes someone's pictures of himself and his girlfriend as "gorillas"[3], which is the sort of error one imagines Google would be a lot less likely to make if they had more African-Americans working on their code and testing their software before release. Or machine learning algorithms that courts use to predict recidivism rates in determining sentencing have much higher false positive rates for African-Americans than whites.[4]
And making this place more welcoming to Curtis Yarvin by focusing discussion on the technical merits of Urbit and ignoring his personal views is a signal to a lot of other people about what we as a community value and what we don't. And I think it's a bad signal, because it alienates people with valuable and important viewpoints that we ought to be finding ways to be more open to, not less.
