A people stripped of their land may be kept on as performers, their songs and dances staged at official ceremonies as a token of 'culture.' The same powers that applaud the dance are taking away the ground it was danced on. Displacement takes away a livelihood and the way of life that grew from it, then sells the leftover as display.
When your heritage is the only thing you have left to sell, withholding it becomes a political act. Someone forced to trade on their traditions can turn that same cultural value into leverage by declining to perform for the people exploiting them. Defiance means asserting rights, not asking for them.
Marginalised people are used from every side at once: by land grabbers, merchants, missionaries, the media, corporations and the state. Each takes something different, whether land, labour, souls, stories or votes. Seen together, these add up to a single condition of being used.
Wanting to preserve a community's traditions against development and migration is not enough on its own. That separateness only holds if the group gains political rights and uses them together as a bloc.
Losing land and farm income pushes entire families onto the road in search of seasonal work in other regions. Once there, they meet a stigma that follows them wherever they go. Even comfortable members of the group run into contempt in new cities, for example over what they eat.
