I can smell the “arrogance,” but do you think any of the claims in these paragraphs is false?
When I read that, I interpreted it to mean something like “Yes, he does come across as arrogant, but it’s okay because everything he’s saying is actually true.” It didn’t come across to me like a separate question—it read to me like a rhetorical question which was used to make a point. Maybe that’s not how you intended it?
I think erratio is saying that it’s important to communicate in a way that doesn’t turn people off, regardless of whether what you’re saying is true or not.
As one data point, my father has been retired for 7 years. He got a PhD in physics and then became a software engineer after deciding he didn’t really enjoy research. He’s interested in LessWrong-y topics like rationality, optimal philanthropy, and some of the areas of philosophy that are often discussed here. He’s read and enjoyed some of the articles I’ve linked him to on LessWrong. He should be a shoe-in, right?
But he didn’t grow up in a time when online communities were a thing. They’re just not part of his life and he has no interest in joining one.
