In this case, the name is really only indicative of where the current canon of philosophical thought identifies the first recordings of these notions as explicit philosophical notions, and has nothing to do with “these behaviors” as were not even talking about behaviors.
The name isn’t meaningless — and I’m not using it from a belief that “western” people are more “individualistic” or something than others, as you and others seem to be implying. Obviously there are plenty of individualistic behaviors in people across cultures.
But the notion of the individual with agency creating a state to protect individual agency is recorded explicitly by Kant and enlightenment rationalism, collectively typically referred to as “western” by philosophers. The OP here was discussing freedoms and values, and I was pointing out that they seem to derive from this notion of the individual, which is only one among many.
Do you also open discussions of Newton’s Law of Gravity with a critique that it’s misnamed because gravity is present everywhere?
Apologies to anyone triggered by this jargon, it wasn’t my intent.
