"Not thriv[ing]" is not the same as being quashed. Minority opinions don't always rise to the popularity or acceptance level of majority opinions, and that's OK.
Let us not use the word "thrive" or "quash" to avoid misunderstandings. To rephrase, I hope that on HN even minority opinions have reasonable rebuttals. Unfortunately what currently happens is people flag minority opinions with no discussion.
"flag" and "downvote" are two different tools with two different purposes.
"downvote" seems more appropriate for for "this is not interesting and should be less prominent".
"flag" seems more appropriate for "this should not be here at all".
By way of an example, on a political story, if you say something merely unpopular, you'll get downvotes and replies; if you say something hateful, you'll (usually) get flagged.
I agree with you, but that's not what happens for polarizing topics that are technical in nature and not political. People on HN seem to flag comments rather than downvote them.
In a way, iirc, it really is. It's as much a "I disagree" as it is "I don't like this". That said, I would like to see more people actually respond in addition to a downvote.
I don't think that's generally a function of the moderators though.
Nope, sometimes I would have a rebuttal but flagging is the better option (constructive discussion is hard without mutual respect, and/or don't feed the troll). Or, the comment doesn't even have anything to refute, it's just disrespectful or it's spam, or both.
I have flagged a few comments but I'm rarely mad.
And if one is mad because of a disrespectful comment, the flagging is probably appropriate too.
Or maybe you misunderstand (on purpose?). I'm saying you attribute those downvotes incorrectly. It's maybe natural to do so as an instinct -- "those people are against me!" -- but on HN it's expected to be a bit more introspective. It's incorrect to say that "people downvote because I'm right" or "people downvote because they have nothing to say".

No it doesn't. To borrow from the law, ignorance requires no scienter. It simply means you lack knowledge of factual or situational context, willfully or otherwise.
