The pictures illustrating this video show us that women are "oppressed" since their birth : they grow up in the atmosphere with a lot of rules established beforehand : to wear the pink and to play dolls when it's a girl, to wear heels and dresses when it's a woman, to have long hair, to wear make-up, to get married and to have children. The central idea of this speech is that the humor can make certain things change as far as feminist cause is concerned. And I'm agree with it, because it's not thanks to the violence (but thanks to the humor) that these changes can become reality. She is also totally right when she says that sense of humor change according to one's culture. For example French and English people are neighbours but as for me I laugh only when the French joke and I really can't understand the english sense of humor.
But to my mind no matter the nation, the humor is already appreciated.
