Project Monarch wasn't pop culture subversion per se, it was based on the "Dr. Green's" child studies where different rule structures based on social queues such as locations or people disintegrate the mind's rule structure and cause borderline personality disorder.

Along with anti-"universal truth" rhetoric & "-ist" insults you can subvert the mind into the cognitive dissonance we can see in modern leftism.

While Arts are typically where subversion occurs as they are all centralized and casting can be selective in an undisclosed manner, if Lindsay was an MKUltra experiment then she was dropped around 2004 from subversive use as she left exclusive Disney use then.

we’ve all been quite content to demean government, drop civics and in general conspire to produce an unaware and compliant citizenry.

We'll know our disinformation program is complete when everything the American public believes is false.

Disney is popularly where child stars are traumatized by their only trusting adult relationship after separation from their parents. Lindsay was a child of a dancer and a criminal who was groomed to be a model with Ford Models at the age of three., so separation would have been seen as easy. 1989-1998 would have provided the window, and see was drug-free and exclusively Disney until 2004 when she ceased to be a child at 18.

Her movie/music career takes a turn as the support falls away and now she is merely a useful idiot rather than a tool.
