All you need to do is read the other comments on this very page and you will see that there are very strict cultural and political norms here too, but for some reason they are invisible as such to those who hold them. They consider their views to be "common knowledge" and "what any reasonable person believes" because they, too, live in curated bubbles.

Any comment that challenges mainstream science, materialism/physicalism, and leftist politics gets downvoted into oblivion here because HN is definitely not a haven for people who "pride themselves on intellectually challenging material."

TL;DR: It's an echo chamber here, too, but most people who hold the worldview that is enforced here often cannot see their own presuppositions, nor do they see that their views are political in nature.

I’d expect this to be down-voted too. It has nothing to do with the article and makes no concrete claims. It’s easy to slag anything in vague terms, but it adds nothing to this discussion.

>Any comment that challenges mainstream science ...

Stupid mainstream science.

>... nor do they see that their views are political in nature.

You don't say. Personally, I respect comments that prove their own claims.

It's not. Downvoting here is much less of a conversation-breaking action than shadow banning, outright banning and trash-comment-polution on other soc. med. sites. Downvoting has it's place, the occasional abuse of it should not be a problem, it hurts you so much because you want your views to prevail but that's your personal problem, not a site problem.

I get downvoted quite often here too but these days I usually challenge rightist politics - mostly due to it being used as an excuse for some wrong action or inaction at the moment. However, most of the time I have no idea if what I'm objecting to is leftist or rightist, I have to think separately to figure that out... but I don't do it because it's actually hard.

I suppose you think you can see your own presuppositions and I'm ready to challenge that. I'm also ready to challenge the notion that only leftist worldviews are promoted here. The world "enforced" is quite misleading too, some tradition does exist on this site, but it's different and a lot more nuanced than central "leftist" enforcement.

> nor do they see that their views are political in nature.

So are yours... A lot of views are political in nature, some realize it, some not, that fact has no bearing on the viability of those views and bragging about it helps nobody.
