It's a measure of how false your first paragraph is that I can't guess which way your imaginary Borg leans. We see roughly the same number of comments denouncing HN for being libertarian as socialist. As far as I can tell, most HN users are neither of those; rather these perceptions are distorted by what one might call ideological enemy bias.
I certainly wouldn't put it that way. But since you sound sure, I'll ask the same of you as the OP: please provide links to specific posts that convinced you of this view. From my point of view it's hard to imagine what those would look like. But perhaps I'm missing something important.
HN doesn't seem to me to consist of like-minded people. If it did, I wouldn't have to spend so much time asking users not to berate each other.
