Ideology

“Ideologies shape the relationship between an individual and culture, influencing her ideas about family structure, gender and sexuality, faith, the function of work, and the role of government, among other things.” (c) Parmaggiore

As an example, I would like to draw your attention to the "Mona Lisa Smile" (2003) is directed by Mike Newell.
Perhaps, this is one of those movies that are so clearly demonstrates an example of how one person who thinks differently, progressively, can affect the minds of many. The entire plot of the film is built around the rights of women, the right to make that choice, that you wish you did, and does not impose your society.

Time events occur in 50s in America, when it was approved for the role of a girl or woman to get married and be a housewife. But the main character is a liberal way of thinking. And she wants to open these borders or limits in their wards. She uses her art lessons to show girls that they should not obey the stereotypes that women are born to be housewives and mothers.

The film's title is also some sense there. "Mona Lisa Smile," Giaconda’s smile hides her real I, therefore, her smile mysterious, and easier to say unnatural. The model went to meet the painter and smiled, but in fact it was not fun... And our life - if we follow the ideals that are expected of you, you cannot be yourself.
