I'm not sure I get what you're trying to say. I think it probably _is_ fair to say that women now produce more culture than men, in aggregate, but I'm not sure that that is evidence for your thing. Like, I'm not seeing cause and effect here.

(Granted, I don't totally buy into their claims that society is more conformist than it used to be in the first place; it's clear that _crime_ has fallen, but there's no particular reason that that should be joined at the hip to non-conformism and their evidence for cultural stagnation is far weaker than their evidence on crime).
