back when divorce laws favored men more [...] men won more of the arguments about small things

I would be very interested in evidence that (1) this was true and (2) that was because of different divorce laws (rather than, e.g., because women's status was generally lower, leading to both effects).

In any case, supposing for the sake of argument that #1 and #2 are both correct, presumably the mechanism is the one you describe -- in which case what matters is not the facts about divorce law but the beliefs of the parties involved about those facts. In the present instance, it seems that what matters is not who actually "owns" the LW wiki, but Phil's and Eliezer's opinions about that.

I don't think Phil's questions seem much less weird in the light of all this.

Perhaps the point you wanted to make [...]

So far as I can see, that has nothing whatever to do with the point I wanted to make. It's probably true, though.
