A spectrum does imply a total order, but I’d argue that the meme stating there is exactly 1 who is the gayest, OOP is referring to a strict total order. I’d also argue that the gayness spectrum allows degenerate states (heh) and as such is a non-strict total order, rather than the strict total order implied by OOP

A spectrum can have multiple dimensions, like the colour spectrum: obviously red is more red than orange, but blue and green are equally non-red.
