Blame it on Fidel by Julie Gavras (2006)

It isn't easy being a kid.  You are a hostage to the whims of your parents and for the lead character in this story this couldn't be more true.   Little Anna de la Mesa, whose father is an emigre Spanish communist and whose mother is a radical feminist, leave their good jobs to join the movement, live communally and struggle for world revolution.  It is 1972-73, when Franco was still dictator of Spain and Salvador Allende has become a popularly elected Communist President of Chile.  Meanwhile Anna is attending Catholic School where she gets the usual Church indoctrination and being the usual materialistic little kid hates the decline in her parents material fortunes and all the strangers that seem to come and go in their smaller home. 

Her mother's parents, who are wealthy, naturally disapprove of Communists and tell her they just want to take all their property, and their Cuban maid is ready to blame it on Fidel Castro, who is of course the leading Latin American communist at the time. 

Her mother writes for Marie Claire and fights for abortion rights, at a time when abortion was illegal in France.  She interviews women who have suffered at the hands of their spouses and has very little time for Anna.  Her father goes off to Chile to share in Allende's struggle.    He also takes his daughter to a mass demonstration in Paris protesting the regime of Franco and they have to flee when the police charge with tear gas and nightsticks. 

Watching this film, I guessed where this story was going to end.  Eventually the overbearing nature of Catholic school and her social

ostracism when she is excluded from catechism class causes her to ask to leave the oppression of nuns in favor of a public school, and she acquires a new sympathy for her father's sadness when he learns from the TV news that Allende has been overthrown in Chile.  

It's a cute story and the child actors are the center of it, for sure.  You are unsure what her ideological destiny will eventually be, but she is learning both to think for herself and to have compassion for the beliefs of her left-wing parents.  Not everyone believes the same things, but that doesn't necessarily make them bad or evil.
