>I cannot, by definition, censor someone. I can ban them from my systems, kick them out of my home, refuse to listen to them and tell all my friends to ignore them, but I can't censor them, because I do not have the power of the state behind my decision. The difference is I can do all of those things, but nobody else needs to put up with my antics. If Dang banned you, you can still talk on thousands of other places.
I would argue that this is definitely censorship. Just because you can go somewhere else doesn't mean you aren't being censored - you are being denied access to the HN audience. Somewhere else isn't going to have the same audience. And that audience isn't making the decision - a small number of moderators are. But you're right that this is just down to pedantic word choice, feel free to discard this thread of the discussion if you'd rather not push the matter further.
>I absolutely agree with you that this argument is used to shut down discussions, but that doesn't mean the distinction isn't important. Just listen to all the dishonest, deceptive bullshit we hear from politicians defending themselves by whining about the First Amendment when criticized, as if their right to speech is a right to be free from criticism. The problem being, of course, that people who don't necessarily know better fall for it and suddenly believe false things about how free speech works.
I'm not here touting free speech like it's a legal right I have as a submitter and an obligation HN has as a publisher. Instead I'm touting it as a damn good idea that makes for a better medium for discussion and suggeting HN embraces it anyway.
