You're attributing a whole lot of agency to things that might have different factors.
I can't downvote becuase though I've read HN since 2007ish, this is a new account. I would, however, probably downvote threads like this becuase out of all 600 comments, I don't think very many people have learned anything and a lot of blatantly false and sometimes racist stuff has been shared by people of every persuasion. I don't think these discussions are productive at all, but it makes people feel good because they're "fighting" for a cause, but they're still just a rate in a cage.
Is the cause of Gaza or Israel bettered by this comment section?
