You've been using HN primarily for ideological warfare for a long time now. Your recent comments in particular have been breaking the site guidelines egregiously and repeatedly. You've pulled this "sleeper account" attack before as well (https://news.ycombinator.com/item?id=23859828).
If you keep breaking the site guidelines, we are going to ban you. Actually, you're well into bannable territory as it is. I'm shocked at how much and you badly you've crossed the line. We've cut you way more slack than most people get here.
If you don't want to be banned on HN, please review https://news.ycombinator.com/newsguidelines.html and stick to the rules from now on. For all its many flaws, this is a community, and to participate in a community while constantly destroying the commons is incongruent. People who use this place need to take care of it, not burn it. That goes for everyone, regardless of what their political views are or how intensely they feel them, and that includes you.
The idea that commenters should "make HN good because we all want it to be good" is quite positive, and that sentiment seems to be reflected here far more than banhappy reddit.
It's better to err on the side of patience generally, and feels more in keeping with the values of the site. There's are also judgment calls about things like who seems more likely to respond to persuasion, how much history the account has, whether it's related to previous abusive accounts, and things like that.
They'll just make another account and start over.
By explaining what the person is doing wrong, maybe Dang can help them be a more productive member of the HN community.
As for HN being "no longer salvageable" - people have been saying these things for 10 years or more. Of course it could have become true after 10 years—I don't want to be complacent. Sometimes the wolf eventually shows up. But there needs to be some evidence beyond simply repeating the things people repeat.
Right-wingers think HN is overrun by Marxists and left-wingers think it's overrun by Nazis. Both sides agree that the mods do a bad job and the site is destroying itself fast. They've been saying that for years. The decisive element here is the passions of the perceiver, not the object being perceived. That's why people's perceptions are so contradictory: what they're perceiving is an inverse of their own identifications. Usually this is based on a few data points that they overgeneralize. I've written about this a lot: see https://news.ycombinator.com/item?id=23308098 for a summary, and https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor... for endless descriptions of the bias at work.
Of course it doesn't follow that criticisms are invalid. We try to be open and often adjust in response. But criticisms have to rise above a certain noise level—they need to clear the "randomness plus cognitive bias equals narrative" bar. When you say "Many people not in the community believe that Hacker News is no longer salvageable," it's not clear to me whether you're talking about serious critics or, say, Twitter ideologues, who have been saying that about HN since at least 2013. Most of that is driven by fashion. For example, small groups bond by snarking about, or denouncing, larger groups. That's all normal social dynamics (and internet dynamics), but I've learned the hard way that if you take those statements literally, it's crazymaking, because they're not really about what they purport to be about. That's not a reliable way to improve or, if you like, "salvage" HN.
All of which is a long way of saying that if you, or anyone, wants to discuss problems with HN, that's great, but we need specifics and links.
1. Be significantly less tolerant towards transphobic comments on this site, such as this one: https://news.ycombinator.com/item?id=23937722
2. Send very clear and very loud signals that transphobia is not welcome here, such as by making a clear, pinned front page post about it. There are going to be a number of people who are going to complain about this policy and talk about "free speech" and "marketplace of ideas" &c, and to them make it very clear that either they get with the program or are no longer welcome here.
