Perhaps, but what you said is unfalsifiable and/or unknowable.

Ideologies are not invented unless you're a caveman. We all got to know the world by listening to others.

The subject of discussion is if and when external forces can alter those ideologies at will. And I have not seen any evidence to support the feasibility of that at scale.

The idea that falsifiability is necessary or good for a belief system is a narrative you are choosing to believe in. :)
