Good write up, appreciate the effort.
I don't think FF7 is to blame for the themes (even Captain Planet probably wasn't deliberate subversion). Its more like their good intentions were followed by co-opters who wanted to capitalize on the effect that eco-savior media themes had on an entire generation after the influence had taken root.
Conditioning can be very generic. They took a generation that took on a vague undeveloped self-understanding of themselves as 'people that care about the planet', and slowly steered them into a controlled (and poison pill) leftism camp, and the controlled right played the part of a Shinra (generic ethically challenged asshole governmental/corporate complex) to a fucking T (talking about the GW years) like it was all scripted face vs heel.
That part was where the real crime and conspiracy happened, and it is a crime because not only did the left fail to protect the planet, they administered cultural poison pills. Anti-natalism, anti-family, a castration cult, an enabling relationship with drug use, mental illness, core beliefs that are nationally/ethnically suicidal, etc.
Millennials and Boomers are old enough to see the formative influence of all of the propaganda, politics, media, and organic(?) social trends of their lifetimes in full hindsight. Can't fix what's done, but if people could navigate the influences around them better. Doesn't matter if they're good intentioned or bad intentioned, influence is a weapon.
