Globalism is just rebranded communism, communism 2.0 but in a new guise and with a different name, due to the negative connotations and history associated with the previous name, details of which are easily available to anyone via a quick internet search.
The idea of rejecting any form of patriotism or nationalism, so we are all one world, is an ideal to which communists aspired. From the words of the Internationale, the hymn to internationalism, and its chorus:
Arise ye workers from your slumbers...
So comrades, come rally
And the last fight let us face
The Internationale unites the human race...
