> But how do you know they’re intentionally trying to stir trouble, vs. being naive
This is not a Hanlon's razor situation. HN has pretty clear guidelines about what a good submission is:
Off-Topic: Most stories about politics, or crime, or sports, or celebrities
This will disqualify lots of CNN/FOX/The Sun/The Critic/Whosit/Whatever tabloid/opinion column content that isn't tailored for HN's audience (putting it nicely). We might disagree with the rules, but those are what they are.
> And do you think it’s a net benefit for posts like these to be flagged vs. visible
No opinion, I consider flagging to be one of HN's most poorly-implemented features. I leave showdead on at all times.
