A lot of it isn't 'climate change denial', it's more a realisation that we don't have realistic solutions, especially while humans continue to do what they always do - fight wars over territory/resources/religion.
May people on HN might have home solar, a heat pump, and a shiny new EV, but expensive green tech that's limited to the middle-class and up in the wealthiest countries isn't going to make much of dent in global emissions.
It’s felt like there's been a serious uptick in incredibly hot headed new accounts the last few months. The number of dead comments I’ve seen in threads lately is staggering. Anecdotal but idk, feels that way.
You can, but only briefly. HN gives you a short “oops window” to delete comments. Officially it’s for typos. Unofficially it’s a dignity rollback mechanism for people who realized mid-thread that they don’t actually understand what they’re talking about.
Eh, even when I understand what I'm talking about, sometimes I submit a comment and then instantly realize "you know what, I actually don't want to debate this with a random stranger on the Internet".
Downvotes on a comment have already affected your total karma score. Deleting the comment doesn't undo the karma loss. However, you have a chance to avoid further karma loss if you decide to delete the comment shortly after it starts getting negative reactions. (I have done this when I realized that my comment was getting downvoted for snark.)
You can nuke your account by doing something completely egregious like challenging someone here to a duel (it's happened! - account and all post history deleted - we don't see the -deleted-- placeholder as much as we used to)
