It’s a whopping two sides of a scale, which doesn’t unambiguously refer to “individualism” or “collectivism”, also referring vaguely to associations with dozens of other issues. So it’s actually a worse way of describing those ideas than saying “individualist” or “collectivist”, because you’re no longer even specifically saying that. And “individualist” vs. “collectivist” is already a terrible way to categorize all political ideas. What does abortion have to do with collectivism? How about zoning laws, or environmental protection?
This is the issue…left vs. right has nothing to do with any one issue, in fact it actually serves completely to distract people from the specifics of issues, because instead of actually figuring out the nuance of something, people fall back on their group identity and go, “well if the leftists hate it, then it must be good, because fuck the left!”
