This is an interesting example - I'm guessing the poster said "obtuse" where he now says "hyperbolic". While "obtuse" is definitely just an insult, literally, my experience is that it's used colloquially with an implied "deliberately" prefix to mean not "deliberately stupid/slow" but rather "deliberately avoiding some truth as a rhetorical defense". Of course, better safe than sorry.

Right, it was edited that way. Commenters shouldn't edit things in ways that undermine existing replies—that's discourteous and can even be passive-aggressive.

Words that imply 'deliberately' are probably best avoided in HN discussion because they're mostly a way of attacking the other person. Another common one is 'disingenuous'.

To be fair the original comment (which is top comment at the time of this writing) is not making a good faith argument.

Commenters here need to follow the rules regardless of what someone else did. Otherwise we just end in a downward spiral, because it always feels like the other person started it.

If by the original comment you mean https://news.ycombinator.com/item?id=23333929, I don't see any indicator of bad faith there. Maybe it's wrong or even very wrong but that's not the same as bad faith.

For posterity, the bad-faith in the original comment is based on the fact that the poster states that tagging something as disputed is itself arbitration. But the act of tagging a tweet as "disputed" is a purposeful deference of arbitration to 3rd parties. In other words, the action is the opposite of what he/she is saying and the poster is either self-deceived or wantonly obfuscating truth and deceiving others - very bad-faith.

I think you're reading that comment overly literally. But even if you're right, the psychological state you're deriving from it does not necessarily follow. You're the one filling in that step, and then using it to attack someone else ("bad faith"). That's the part we ask people not to do here, for what should be obvious reasons. Before you get to "the poster is either self-deceived", your post here is a fine critical comment and could easily just stop there.
