HN is not a living organism, it’s an abstract entity formed by the people who engage in the site. As it happens within any community, there’s no such thing as consistency. In fact, so diverse is this community that I’d wager that luck and chance explain much of what gains traction or gets flagged here.

Majority of HNers are obviously left-leaning, and left-leaning political views always get much more support than right-leaning political views.

HN not abstract entity, it is full of living organisms with biases and majority view carries the day.
