Mexico.... It's Mexico. There is no point or your comment.
United States of Mexico it's like saying The Republic of Colombia, or maybe in your case, United States of America, those "names" are just available to say it when a reunion gets more international and formal. Your logic does not making any sense lol
As people from others countries know your country is just United States, not the name as constitution. Your country it's not America, America it's a continent, otherwise How would be named our continent??? Do youu have a name for the whole continent instead of America??? Probably you don't LMAO.
Cristobal Colón has "discovered" our continent as America, therefore AGAIN, there is no point to call your country as America. Do you need more arguments until the point on having a fight without sense???. You are the person who needs badly to grow up, because really, it was annoying to saw that co-relation of your saying "Bahhh, Mexicans are also U.S Americans cos they named as United States of Mexico", I mean uhhhhh, so cringy lol
