Thank you for your response! It does help to be able to discuss these things, even if it seems a little meta.

A single downvote is not an expression of a community norm.

Point taken.

The "someone at LW doesn't like what I wrote" part is accurate. You don't need the "oh no" and ":(" parts.

Sure, I don't need them. I included them as evidence of the type of flawed thinking I'm trying to get away from (If you're familiar with Myers-Briggs, I'm an F-type trying to strengthen her T-function. It doesn't come naturally).

Personally (and I did not vote on your post either way), I don't think you are quite engaging with the problem posed...

You're right. I noted that problem, but evaluated it as being less significant than the specifics of the extended example, which struck me as both morally suspect and, in a sense, odd: it didn't seem to fit with the tone of most of the other posts I've read here. See my reply to dbc for more on that.

It is up to rationalists to find a way to organise collective actions that require a large number of participants for any chance of success, but which everyone would rather leave to everyone else.

I agree. I'd add that those actions need to be collectively decided, but I agree with the principle.
