Nope. A Christian theocracy of Puritan values.

From Atwood herself (https://lithub.com/margaret-atwood-on-how-she-came-to-write-...)

"The deep foundation of the United States—so went my thinking—was not the comparatively recent 18th-century Enlightenment structures of the Republic, with their talk of equality and their separation of Church and State, but the heavy-handed theocracy of 17th-century Puritan New England—with its marked bias against women—which would need only the opportunity of a period of social chaos to reassert itself."

God forbid we notice any similarities not approved by the author. How silly of me to think it could be about anything other than the religion and cultures where gender equality is the highest.
