How does one downvote a comment on HN? I thought maybe there was some reputation or age requirement, but I've been here a while now & I still don't see any option to downvote comments.
I think you need over 500 karma to downvote. I couldn't downvote for my first few years here (and I probably only downvoted posts once or twice since I could)
I actually upvoted @DanielBMarkham, because I thought his comment added value, and he did explain very well that it wasn't aimed directly at my post! :)
My point was more that if you're being 'punished' for a comment, it's not the person you're replying to that is doing it - that is, it's not the person asking for the explanation that's punishing it.
I think that the GP is being unfair, though. Complaining about arguments specifically on the topic of politics? That's the essence of politics - conflict and how to deal with it. If people didn't disagree on a topic, it wouldn't be political. Outside of political topics, I'd say the bulk of explanations offered on HN are upvoted or at lest left neutral.
