Edit: I should say, she's actually pretty on board with the rich/corporations fucking up the world, but she blames black people, poor people, immigrants, young people, for their problems instead of seeing the larger implications.
Maybe a specific episode of Chapo, Citations Needed, documentary, etc, whatever, she's what I would call a very conservative lib
The Dollop is great because it's mostly comedy and if you pick the right episode order, the politics sneaks up on you. The only problem is the vulgarity and cursing if she's against that kind of thing. Behind the Bastards is also good if you start in the right place, but again the cursing. I wouldn't start out with Chapo just because the irony and style of humor and requisite internet-brain-ness. There's the Yes Men Fix the World documentaries. Enron: The Smartest Guys in the Room. Hypernormalisation. Some More News on youtube is probably pretty accessible too.
