@nex3 I've been describing it that way (well... "multidimensional continuum") for years! https://htyp.org/gender/101
more like a math-based beef: when working with sets, each application of the intersection operator whittles the scope of the resulting set. it is, in essence, a limiting, divisive function.
The union operator, on the other hand, supports broadened perspectives and inclusion.
The math-informed discussion above makes me think I could find some appreciation for the dissonance these usages present me.
Ahh, yes, I see your point.
Staying more or less within mathematics, I'd say "intersectionality" derives more from network theory than from set theory in that an intersection (technically "vortex") is a place where lines ("edges") converge.
More practically, I think it's intended to evoke a navigational metaphor -- an "intersection" of multiple roads.
In a sense, tho, it *is* intentionally restrictive in that something is only intersectional if it has more than one path.
