The word “America” is not reserved for the USA alone and belongs to the entire Americas: North America, Central America, South America. As such if they want to rename the Gulf of Mexico then it should be the Gulf of North America of which both the USA and Mexico are a part of and share borders around that body of water.

Furthermore the word “America” isn’t an English word but the German bastardization of an Italian word. Specifically the word “America” was coined by Martin Waldseemüller a German cartographer who named the Americas after Italian explorer Amerigo Vespucci who explored the new continents for Spain and Portugal. So I guess the Gulf of North Amerigo is more accurate. LOL.

In any case, if this is the big orange blow-fish’s attempt to dis on Mexico then it’s pretty petty much like everything he does to massage his massive ego.

One way to counteract a conspiracy theorist is counterintuitively not to argue against them but instead simply ask “Ok, well fine, how will this theory make your (and/or our) life better in the here and now?” Keep the theory circling back to them and their life so as to get them to self-reflect as why they really want to believe in such a theory because that is the real issue that you should be addressing, not the theory itself. This method is better in face-to-face discussion and needs a lot of patience.
