Why Are Chemtrails Being Digitally Added to Old Movies?

According to a newly published article, Chemtrails have been popping up all over TV shows, movies and commercials for a while now. Even video games and cartoons are adding these trails to what would otherwise be clear blue skies — why do that if not for propaganda purposes to normalize everyone to what’s going on in the skies above our heads?

One episode of CSI NY even featured a conspiracy theorist professor as a victim, someone who actor Gary Sinise’s investigator character on the show called “totally anti-American” because the professor believed in chemtrails and water fluoridation. (They don’t elucidate either that he believed water fluoridation is poison purposefully added to the water to, say, dumb people down or anything, they just say the professor believed in water fluoridation — I guess believing in water fluoridation at all period is anti-American? Way to go writers.)
