In a way your emphasis on the importance of demographics over politics does make sense since the very "lefty" societies of more heavily-white Scandinavian countries apparently is as unavoidable there as it is in heavily non-white nations.

IOW, leftism is a negative dynamic throughout the world, in both largely white and non-white societies. So population characteristics do have to take front and center since the idiocy of liberalism/leftism/progressivism/libtardism exists throughout the world.
