I dislike fringe libertarianism but my experience here is the opposite - I notice posts, sometimes I reply to them, I'm often downvoted by those commenters, but it's not a central element on HN, and I don't feel it dominates the narrative.

There is a silent upvote majority here who will un-down almost anything that isn't clearly toxic or counterfactual.

So I certainly do appreciate the level-headedness here.
