The hidden lesson of 1984 is there is no answer once identity politics are in play. "Four legs good, two legs bad." is already past the point of no return and there is no "a society" as you quote but two battling for supremacy. Historically we have little evidence of solutions other than civil wars. Asking how to roll back identity politics without a physical war is like debating strategies to avoid nuclear war after the missiles have launched but before the mushroom clouds form. Its a little too late for that and there really isn't any point in wasting limited time in trying to roll back or blamestorming in circular firing squads.
