I didn't claim that was his motivation, I claimed it was the practical outcome of urbit, and it is. His presence prevented a great many people from attending lambdaconf because they had a legitimate fear of the racist violence he advocates, and refuses to recant. You'd have to work a lot harder apologizing for fascist bigots to make me feel any embarrassment for calling out their negative impact on communities I care about.

Claiming politics is out of scope is absurd, and is a rhetorical mechanism designed to, at a minimum, preserve the status quo. His politics are abhorrent -- accepting his declaration of them as irrelevant when they're anything but is effectively siding with them.
