On the one hand, of course the whole world matters. On the other, we can make much more specific claims about smaller regions, and test them more easily.
In this particular case, I think both are overwhelmed by concerns of conversational pragmatism. If you can defeat his arguments in the framework where he made them, you win. If you make an objection outside that domain, and he says “but that’s not what I meant”, then squabbling about particularities of domain, word choice, and inference is a frequently observed failure mode. Noting and criticizing US-centrism (or any other -centrism) is worth doing, but should be considered an aside.
