I've read both of Yarvin's Medium posts. I think perhaps you only read one of of them. Given the degree of stridency in your objection to my comment, I'm guessing you also haven't carefully read the Mencius Moldbug posts that kicked all this stuff off (that's fine: he writes in a deliberately obscurantist fashion in order to foment exactly these kinds of misunderstandings).
A few weeks back, one of the most ardent supporters of his Lambdaconf talk (who went on to raise a not-insignificant amount of money to help sponsor it!) reported attending a Founders Fund event with Yarvin. In person, Yarvin was evidently so flagrantly racist that he was ostracized by other attendees.
Doubtless, Yarvin would respond by objecting to the concept of race, or to the assertion that "suitability for slavery" is a bad thing, or that intelligence is generally a good thing, or by juxtaposing some ridiculous bit of pop culture ("do you believe in the Holocaust? Well, I mean, you're saying the Holocaust as portrayed in Inglorious Basterds...?") against the circumstances of Epictetus, or whatever the fuck else is in his tiresome bag of rhetorical tricks.
People aren't making this stuff up about him.
