No. I'm saying once you smooth over five or ten year periods, that it is empirically false that the Overton window in North America is moving rightwards.
It may very well feel that way to people who live in strong bubbles, but it just isn't true across the general population -- which of course is how the Overton Window is defined.
How does 'moderate positions now would be extreme in the 90s' act to bolster that contention, without the unsaid requirement that 'any included tolerance or added human rights that didn't exist more than a decade ago means de-facto left-wing Overton movement', which precludes any democratic society from having the Overton move right?
