Something I learned a long time ago is that it doesn't matter how well you argue a point with a nincompoop, they will simply shrug and repeat their horseradish verbatim in the next thread, hoping that next time they don't attract an audience with as much critical thinking. Unless you are willing to waste as much time as they are arguing on the internet, it's a fruitless endeavor.
It's really up to the moderators of a social space to keep bad faith nincompoops out, and Hacker News has shown themselves to be complicit and unwilling to do what is necessary to prevent its own enshittification. At this point, this place is just Reddit with a tone policing and a nuclear downvote button.
The tech community was the source of the largest threat to American science in a century. As cheesy as it sounds, I think its my duty to counter the lazy talking points that otherwise go unaddressed in these circles.
That does help, and is part of the reason I myself engage with these folks from time to time, but it requires discipline to recognize when you're throwing good effort after bad.
You want to give your voice the greatest chance of being seen. Strategically responding to upvoted bad faith in a highly visible thread is a good idea. Keeping an argument alive 5-6 levels deep in a subthread that was already flagged is less so.
Hacker News is Reddit with a tech-supremacy mindset.
