Well, if it's hardwired, isn't Trudeau's vaunted post-national state a sociological absurdity? Actually, what I think he might mean is that we aspire to be a post-tribal or post-ethno-racial state but if that's the case pursuing the inherent tribalism of identity politics seems a counterproductive way to get there. I think Trump has figured the tribal game out and realizes that all you have to do is convince your preferred tribe of the validity of its sense of victimization. It doesn't mater if the claim is rational or logical. It merely needs to appeal to a collectively held insecurity. And in this all tribes are really the same. That's the double-edged sword quality of identity politics, although progressives are no doubt loath to admit it. Trump's been playing their game.
