that was definitely not the vibe i got from infinity train season 3 at all haha, i thought that season ruled. i mean grace and simon were definitely being "rebellious," but in a way that was closer to something like the warriors than any sort of real world progressive movement. it was teenage rebellion where they just wanted have a secret club where they can misbehave with no adult supervision, not a movement to fix society on the train. and yeah, right wingers might accuse young progressives of behaving like that, but to me it's pretty clear that that's not the argument the show is making

if anything it's probably more easily read as being about outgrowing solipsism, with grace and simon initially only caring about themselves and not caring about the lives to the denizens of the train because they don't view them as "real." and if you wanna attach a political argument to it, that "fuck you, got mine" attitude and the way they view certain peoples' lives as inherently less valuable and worthy of empathy (even inventing a derogatory nickname for the denizens) are the heart of modern conservatism lol
