that's true about assertions, but blindly saying "Fact check!" is still an attempt to offload a wished-for effort onto other people while simultaneously sowing seeds of discernment and distrust into the topic.
What happens when someone yells "Fact check!" at absolutely true things constantly? It erodes confidence. That's why "Person yelling fact check" isn't a typical or generalized role in normal discourse.
Yes, it's good to correct the incorrect. How does one do that typically? A rebuttal.
A supposed 'deferment to experts' on the internet is worth next to nothing, just a way to paint yourself a bit more altruistically while producing FUD.
I asked if anyone could rebut it. Normally I'd do the work myself, but I'm not very up to speed on this stuff and I wasn't in a good place to do a bunch of research, and someone who's been following it more closely could probably do a better job pretty quickly. The comment smelled like a possible propaganda account to me, making what I thought were some pretty wild claims, and the commenters that were there were piling on because tribalism, so I was trying to act like an antibody in HN's immune system against nonsense, and flag it. Sorry if it sounded like a demand, it was probably too terse.
And it's worse than spam when someone is posting incorrect things and people are downvoting people questioning it. As another user has already posted, the Iron Dome does not use the same radar they are talking about and is not "blind"
