This interests me on two fronts. I hadn't realized there was any backlash against Japanese Prime Minister Shinzo Abe's efforts to undo some structural sexism. And as Noah Smith says:
So if Abenomics succeeds, the thinking goes, Abe might be able to push Japan in a xenophobic direction. But that doesn't explain the particular venom many gaijin writers have toward the Womenomics part of the program. I have a hypothesis to explain this: Abe stole their issue.
You see this all the time in politics. Democrats gave Bush little to no credit for the Medicare expansion. Republicans gave Clinton little to no credit for scaling back welfare. And so on. When a leader of the Enemy Party does something you've long been calling for, the instinctual response is to A) discount it as tokenism, and then B) deride the Enemy Leader for engaging in tokenism.
