I'm trying to steelman your arguments as much as I can, but I find myself confused. The best I can do is: "I'm worried that people would find LW communities unwelcoming if they do not go to rituals. Further, I'm worried that rituals are a slippery-slope: once we start having rituals, they might start being the primary activity of LW and make the experience unwelcoming even if non-ritual activities are explicitly open, because it feels more like 'a Church group that occasionally has secular activities. I'm worried that this will divide people into those who properly mark themselves as "LWers" and those who don't, thus starting our entropic decay into a cult."

So far, your objections seem to be to this being the primary activity of the LW group, which -- honestly -- I would join you. But if a regularly meeting LW group also had a Catan night once a week (for Catan enthusiasts, obviously -- if you don't like Catan don't come) and a Filk night once a month (for filk enthusiasts, again), I am not sure this would hasten a descent into a Catan-only or filk-only group. Similarly, if a LW group has a ritual once a year (or even if every LW group has a ritual, and even it's the same ritual), it doesn't seem likely rituals will become the primary thing the group does.

"There is a rather enormous difference between things I care whether lwers do and things I care whether lw does."

I notice I am confused. LessWrong is a web site, and to some extent a community of people, which I tend to refer to as "Less Wrongers". If you mean these words the same as I do, then I do not understand -- "LW does something" means "the community does something" which means "many members do something". I'm not really sure how LW does something is distinguished from LWers doing it...
