What is your personal definition of "globalism" ?

As has been discussed at great length since 2016, "globalism" often acts less like a fixed definition and more like an umbrella label whose meaning is supplied by the surrounding story/argument. The term can be used for an established policy-oriented usage and a conspiratorial usage centered on a purported hidden cabal. It's completely malleable and shifts with the speaker and conversation to create the perception of a boogeyman. In many cases I've seen the kernel of truth fallacy used for irrational extrapolation.

For example, an online content creator might start with a concrete complaint about a trade agreement, move to a broader objection to international institutions, then suggest that immigration, climate rules, and trade are all parts of one plan. "Globalism" lets the argument move between various observable processes, disputed policy judgments, and claims of secret coordination without clearly announcing the shift.

What is your personal definition (since there is no one singular definition)?

Here are the most common variants I've seen used in place of "globalism" to help you mix and match. Clearly, since it's a personal term with no operational definition, you can add more from outside the list.

Global interconnection
The most generic version that encompasses trade, migration, culture, communication, etc., without necessarily a government agreement. The blending of cultures and races are common complaints/threats.

Market agreements
Trade agreements among countries for more open trade, migration, finance, etc.

International governance
These are your state agreements creating extranational governance among member states. Typical complaint/threat is losing sovereignty (typically where "they" exert control).

International agreements
This is simply any agreement, treaty, etc. between states (a recent addition).

Immigration/Cultural
This is less state-based and more cultural in nature. Here “globalist” often labels people perceived as putting cosmopolitan values above the nation. Typical complaints/threats involve loss of culture and racial demographics changing.

Technocratic globalism
This is the mixing of private technology and public governance. This creates a palate from which almost any technological threat can be painted. This is becoming really integrated among other variants with AI.

Thinktank globalism
This is your NGO "think tanks" that become demonized as controlling the world. Historical examples are WOMP, The Trilateral Commission, and the example du jour: WEF.

Elite network globalism
The belief that wealthy executives, officials, financiers, and organizations pursue common interests across borders, often at ordinary citizens’ expense. This can mean a critique of observable influence and lobbying—or an unsupported leap to a single coordinated command structure.

"New World Order" globalism
Similar to the elites, but with more specific goals. A purported covert plan to eliminate national sovereignty and impose centralized world control. “Great Reset” narratives often place otherwise unrelated events inside that alleged plan.

Antisemitic globalism
Here "globalists" function as codewords for your typical Jewish conspiracies alleging they control world governments, typically based around "international banking". Tell tales here are references to the Rothschilds and/or Sorors.

In the alternative, listing specific actors involved in your version of "globalism" and, more importantly, actors/states who oppose globalism. I imagine the grouping of oppositional forces/actors will be more illuminating for your concept of the term rather than a specific operative definition.
