I think that nationalist is not that bad an 'ist to be called; I would think that all patriots would be nationalists at heart. I also suppose that there have been more than a few members of other races who love their country as well, so Black, Asian, and Native nationalists are all a good thing too as long as we're all promoting our Constitutional US government.
I have long suspected that our internationalist (Communist) "friends" in the Democratic party ('fa-ha-ha-ha) really want to break the country's back with an unsustainable welfare system. I suspect that the "Medicare for all" crowd hopes changing the health care industry from being a highly goobermint regulated corporatist industry to an absurdly regulated inefficient socialist enterprise will eat the defense budget so the US can't "bully" the rest of the world.
