Malcolm in the Middle: Francis led his classmates in the military school into a hunger strike when their TV is confiscated. When the Commander was about to give in, he instead realized the hunger drove Francis unable to be good enough of a negotiator to turn down a ridiculous counter-proposition.
In Brazilian show "A Grande Família", there was one episode where Agostinho Carrara took a test for a Government job. When his family refused to believe he didn't buy an answer sheet, he went into a hunger strike that lasted until the results came and revealed he failed, thus proving his innocence. Arguably, he could have solved it earlier if he told them he only didn't buy because he and the man selling answer sheets didn't agree on a price.
In a later episode, his mother-in-law went into a hunger strike for unrelated reasons and it seemed people forgot Agostinho's previous one.
The Simpsons: Inspired by Cesar Chavez'shunger strike, Homer Simpson of all people started one to expose the local baseball team's plan to move to Albuquerque. He chained himself next to the skeleton of someone who went into a hunger strike for a bathroom-related protest.
Sounds like this is going towards a split with "rejection of hospitality as a protest against having been kidnapped", which is not limited to food, and Hunger Strike. I think both tropes would need more examples. Perhaps they should go through YKTTW.
The current proposal is to split I'm Not Hungry into two tropes: one about refusing hospitality as a form of protest against being held captive (typically in a Gilded Cage), the other is Hunger Strike, refusing to eat as a form of nonviolent political protest.
At any rate, I think we'll need some description for both tropes. I have no idea how to write them at the moment.
Anyhow, do we agree on turning I'm Not Hungry into a disambig between the two tropes in the crowner.
