HN is traditionally quite pro-US to the point that many here were defending Boeing during the 737 Max fiasco. Not to mentions the vitriol against the EU when it fined American tech giants.
I find it amusing or at least ironic that you say "many here were defending Boeing during the 737 Max fiasco" when in reality the mainstream opinion here is very anti-Boeing and there is a down-voted and dead comment that says they didn't see anyone defending Boeing. Well of course, those people are/were a tiny minority so they got down-voted and buried like that comment. It's a perfect illustration of what it's asking about.
And this is going to get down-voted because of the first of fight club.
There are a lot of users on both sides of the topic, just like there on other controversial topics. But it always feels like the "mainstream" opinion is being the one most opposed to your own. The confident generalizations people make about HN are nearly all based on this feeling. That's why they contradict one another.
I'm "anti-Boeing" here though and even I don't see much controversy. Everyone who isn't down-voted seems to think Boeing is solidly at fault to varying extents. There's no hostile media effect going on (from my POV on this issue).
There have been plenty of comments defending Boeing and not being downvoted, though probably not as many as are critical. That's a function of it being an indignation story, though. Indignation always wins.
