Cultural norms are diffuse and propagate on their own. It's silly to try to attribute it to John or Bob or Jill.
Likewise, culture is a complicated social phenomenon which has a life and a logic of its own.
It is cultural norms- of women. Making choices. In the real world.
It's simply women's revealed preference.
And maybe they'll try some vocal complaining to try to shift the preferences of the group. Which could work out, especially if a lot of group members don't have strong preferences and are just going along with the existing default.
