A pretty interesting alternate history to write would be one in which the two mainstream poles of Western politics would be 1) religious Christians who believe in converting all of mankind and equality between classes etc. and 2) secular liberals who are diehard believers in Darwin, “survival of the fittest”, support eugenics, oppression of what they think are “inferior races” etc. Don’t know how I would write such a story nor do I know enough about Western political history to really do anything but that’s an idea. “Secular nationalists vs religious internationalists” was/is an actual distinction that exists, mainly in Muslim countries, fwiw so imagining a western version of it shouldn’t be too difficult.
