What dog whistling drivel. That dude's trying so hard to use fancy words and walls of texts to defend his racist views without stating them outright. This is coming from a person who previously said:
"One quality that's a really bad indication is a CEO with a strong foreign accent. They must be clueless if they haven't gotten rid of their strong accent."
Already going mask off in public and later doubling down on it in his blog. Just imagine what his views are in private if he goes to those lengths to try and fail to morally justify them.
Edit: I found the context around it, at least. Seems perfectly reasonable. [1]
"Recently Inc published an interview in which I said we'd noticed a correlation between founders having very strong foreign accents and their companies doing badly.
Some interpreted this statement as xenophobic, or even racist—as if I'd said that having a foreign accent at all was a problem.
But that's not what I said, or what I think. No one in Silicon Valley would think that. A lot of the most successful founders here speak with accents.
The case I was talking about is when founders have accents so strong that people can't understand what they're saying. I.e. the problem is not the cultural signal accents send, but the practical difficulty of getting a startup off the ground when people can't understand you."
