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.
