That you had the definition of globalism literally at your fingertips and still failed to see Musk for what he is is fascinating.
Anyway, your follow-up comment is irrelevant to the matter of your stated belief that Elon Musk is an anti-globalist despite the fact he routinely demonstrates otherwise -which raises the question of why you're now trying to steer the conversation away from said professed belief rather than address it.
Also, thank you for posting a definition of "globalism" undercutting your assertion concerning Elon Musk's position on globalism as well as demonstrating you did not take ehxortation to think about the disconnect between said definition, your belief and Musk's actions.
So now that you've made clear you don't actually oppose globalism, rather you simply object when organizations you don't like engage in said same, let's talk about your professed belief that Elon Musk opposes globalism in the light of available evidence.
What is X (nee Twitter)? It is an international social media platform accessed by politicians the world over. One might even be so bold as to accurately describe it as a global forum.
Where is Elon Musk of late? Firmly wedged in Trump's ass, whispering in his ear, wrangling for a position of influence wherein he would be a driving force behind policy decisions about the operational structure of the federal government.
What has Elon Musk been up to? Oh, nothing much -just having 1-on-1s with world leaders, prancing around on the geopolitical stage, sticking his fingers various political pies all over the planet.
Ergo, despite your belief, it is evident Elon Musk does not oppose globalism so much as he wallows in it as one of the world's most visible globalists.
