I downvoted this post not because I hate you, or because I love Eugine_Nier (o), but because I’d like to see fewer post like this one in the future. And I think that expressing my sentiment is what the “Downvote” button is for.
More specifically, I don’t think that public shaming and witch hunts belong on Less Wrong, even when the person being hunted is actually a witch (oo). I think that the toxic culture such tactics create is likely to be more harmful than individual unruly posters, in the long term.
(o) I don’t even remember who he is, though the name does sound familiar.
(oo) Metaphorically speaking.
The word “utilitarianism” technically means something like, “an algorithm for determining whether any given action should or should not be undertaken, given some predetermined utility function”. However, when most people think of utilitarianism, they usually have a very specific utility function in mind. Taken together, the algorithm and the function do indeed imply certain “ethical obligations”, which are somewhat tautologically defined as “doing whatever maximizes this utility function”.
In general, the word “utilitarian” has been effectively re-defined in common speech as something like, “ruthlessly efficient to the point of extreme ugliness”, so utilitarianism gets the horns effect from that.
