The argument of the original post is that we shouldn't exclude Yarvin because it might make avowed racists feel unwelcome at FP conferences. To which I say: who cares? I don't want Yarvin at FP conferences, and I suspect none of the attendees particularly do either.

I'd imagine there's a solid overlap between Hacker News posters and people who might attend a functional programming conference, and judging by this comments section your position is in a distinct minority. So if it's OK to ostracize people based on their unpopular political opinions, you may find yourself in the hot seat you've been preparing for Yarvin.

How about this: perhaps we should instead strive for a system of pluralism and tolerance where we don't bring our political disputes into the professional sphere.
