It obviously isn’t, seen by the widespread usage of the term across the political spectrum
The attempted rebranding of globalist into jew is a very recent fringe phenomena. Globalism has been the explicitly stated ideology of Liberals for decades, they self-proclaim as such
I repeat, show me anti-globalist leftist lit pre-2016, I've never heard the term used leftistly. It was alex jones fodder for decades, not sure why we should use it instead of imperialism/liberalism.
Liberals often talk about “globalization” in the economic neoliberal capitalist sense, and in the 90s it was very common to be pro-globalization and anti-globalization. It was what the famous Seattle protesting WTO was all about, the anti-globalist vs. pro-globalist split in the new post soviet left
They are similar in meaning and derived from the same root, but globalization is a much more common word. That's the reason fascists adopted the term globalism: because globalization was used by leftists.
