Obviously there is not one topic that will cleanly divide everyone in the US into two categories, but if you wanted to partition the population into two clusters as cleanly as possible, what would that topic or set of topics be?
This seems like a type error to me. The two groups have an importance disagreement: one group feels that X is kinda important, but Y is Holy Shit Very Important, so Y should override X; the other group feels the opposite. (For example, X = “the marketplace of ideas” and Y = “the plight of people at the bottom of power relations”.) So to one group, the dividing line is about Y, while to the other it’s about X. The war isn’t a factual disagreement, it’s a bunch of people shouting at each other “X is important!”—“No, Y is important!” and then retreating to their bubbles to reassure each other that “X is important”—“Yes, yes, X is important” and then back into the fray again.
