Drinking the Orange One's Flavor-Aid
Repeat after me:
There are _three_ countries in the North American Continent. In order of size, that would be Canada, the United States of America, and Estados Unidos Mexicanos. (Depending on who you're talking to, adjacent islands such as the Bahamas, Bermuda, and Greenland, but not, repeat, NOT Cuba, may also be included under the heading of 'North America'. The Aleutian islands and the islands in the Canadian Arctic are also part of North America; the Hawaiian islands are not.) (Yes, there are _two_ countries with 'United States' in their names in North America. Referring to the second largest country in North American as the 'United States' alone is... insufficient.)
Removing Mexico from North America is something that certain people in the US have been doing for some time now. It has escalated in the Trumpanze Era. There are those who, until forcibly corrected, insist that New Mexico is not part of el Collosso del Norte, much to the amusement of citizens of Estados Unidos Mexicanos, very few of whom want New Mexico back. Particularly after certain events in the decade and a half starting 16 July 1945. (Look it up.)
And, oh, yeah... the boyz'n'gals at Jonestown drank Flavor-aid.
