> How can filtering infringe free speech? People can say whatever they want, but why should I have to hear them?

Simple. There's people agitating for free speech on idealistic terms, and then there's people agitating for free speech because they have an agenda and want a captive audience.

You can even see it in this comment thread. Take a look around and see if you can find any greyed-out comments that are arguing against the pro free-speech crowd. Down-voting is censorship via mob rule, so that should be twice as distasteful, but yet you see greyed out comments. The folks doing that are the latter, and not the former.

I advocate free speech idealistically. In case it wasn't obvious.

I don't want filtering that's imposed by sites or their users. I want filtering that's implemented locally. I'm OK with opt-in filter lists, such as those used by ad-block extensions, as long as they can easily be customized. But I'm not OK with server-based filter rules that prevent me from ever seeing stuff.

On HN, I have "show dead" enabled, and I occasionally vouch for dead comments.

Hold on, "down-voting is censorship"? Since when? The content remains. No disciplinary action is taken against anyone who's comment starts to turn grey. It's simply a feedback mechanism members of this forum use to signal to each other the quality of the content being posted. The analog would be if people here started mass down-vote campaigns against a person because they posted something off-beat, or if we all started petitioning mods to remove content we found uncomfortable.

You generally gravitate towards down-voting unhelpful, out-of-place, or in some way inaccurate content not simply content you don't agree with, BTW. More often than not I see comments start to turn grey because they miss the point and/or aren't really useful contributions to the discussion. Good points, despite the position being argued, tend to remain opaque.

If one fails to stay within the boundaries of HN's Overton Window, you run a high chance of being rate-limited for "starting flame wars", regardless of whether you were the one who actually started it. What comes after that I'd rather not find out so I try to keep my opinions to myself as much as possible. Whether downvotes are used to detect instances of dissenting opinions is unknown, but it's one of the most obvious ways to discover it I'd think.

You do not actually know this, it is a heuristic prediction. Even getting a half-accurate feel for that would require access to voting data and a lot of time reading over downvoted comments.

People often do not even know why they themselves are doing many things, such is the nature of the human mind, that evolved to optimize for speed over accuracy.
