My KSM post prompted some discussion of the Golden Rule in the comments. I have never found the Golden Rule (in the traditional "do unto others as you would have them do unto you" formulation) all that useful. As pointed out in the comments if your natural inclination is unduly selfish then following the Golden Rule will be unduly generous to others (and vice versa). But I think what most people actually mean by the Golden Rule is something like "when interacting with another give their interests equal weight with yours". This will produce more sensible results but may adversely affect third parties. Also it still depends on your possibly weird preferences. So my preferred version is "do unto others as the community as a whole would want you to".
This has the advantage of providing a reasonably objective decision procedure. It is open to the objection that it will perform poorly when the community as a whole is (for example) a collection of bloodthirsty maniacs. Some might prefer "do unto others what is in the interest of the community as a whole". But this assumes the actor's moral judgement is superior to that of the community as a whole which is impossible as a general rule and will tend to encourage the actor to rationalize his selfish preferences.
In any case I don't see much comfort for KSM in such community based rules. Even granting that KSM is a member of the community which I am unwilling to do.
