> Functional programming doesn't even directly oppose OOP, it opposes imperative.

Just to be pedantic, OOP is (a kind of) imperative programming: goals are achieved by performing a sequence of actions in the world. In functional programming, goals are achieved by defining values; the evaluation order is an implementation detail.

It could be argued that OOP is "more imperative" than, for example, procedural programming, since in an OOP approach, "the outside world" includes everything other than the current object (due to dynamic dispatch).
