The executive orders are ridiculous/childish/whatever-you-call-this. That aside, if they have any legal effect, I’d expect a map company to call a feature by its legal name. Should a rendering of the land bordering the Southwest corner of the Black Sea show the city of Istanbul? Or must it remain depicted as Constantinople? Or perhaps even Byzantium?
Technically the border goes through the middle of the lake, and each side has their own legal name. Is it legally one lake with two names, or two lakes with one name? What should customers in neither country see displayed? What if the federal government renames New Mexico to New America, but the state government refuses?
People want to be angry about this even if really doesn't matter, so they get into hysterics about how "is it really two lakes with one name" brain rot.
Do you think South Korea calls the Sea of Japan that?
