I don't understand how those two sentences are related. I've never heard a political or ideological battle explained as being "curiosity destroying".
As a quick heuristic, if there are more than 150 comments, there's a high probability that it's descended into either an ideological battle, or an obtuse snark-fest over semantics or edge cases.
It’s a symptom of an imperfect commenting system.
With a better system, just like in real life, I would more easily be able to only pay attention to the things I want to pay attention to.
I've written about the pros and cons of the non-siloed format here, if anyone's interested: https://news.ycombinator.com/item?id=23308098. It leads to a rather paradoxical situation.
