Correct me if I'm wrong, but it looks like you're talking about anti-deathism (weak or strong) as if it was a defining value of the LessWrong community. This bothers me.

If you're successful, these rituals will become part of the community identity, and I personally would rather LW tried to be about rationality and just that as much as it can. Everything else that correlates with membership - transhumanism, nerdiness, thinking Eliezer is awesome - I would urge you not to include in the rituals. It's inevitable that they'd turn up, but I wouldn't give them extra weight by including them in codified documents.

As an analogy, one of the things that bugged me about Orthodox Judaism was that it claims to be about keeping the Commandments, but there's a huge pile of stuff that's done just for tradition's sake, that isn't commanded anywhere (no, not even in the Oral Lore or by rabbinical decree).
