Oppression is the exercise of authority or power in a burdensome, cruel, or unjust manner.
Social oppression is the socially supported mistreatment and exploitation of a group, category, or team of people or individuals.
"Institutional Oppression occurs when established laws, customs, and practices systemically reflect and produce inequities based on one’s membership in targeted social identity groups. If oppressive consequences accrue to institutional laws, customs, or Practices, the institution is oppressive whether or not the individuals maintaining those practices have oppressive intentions."
Several movements have arisen that specifically aim to oppose, analyze and counter oppression in general; examples include Liberation Theology in the Christian world, and Re-evaluation Counselling in psychotherapy.
I cannot wait or stick around
I'm giving up, I'm face down
It's not me, it's not you
But I'm still in this room
Hey, you choose it
Hey, you abused it
It's not you, wipe the tears aside
And you cry and scream
In the middle of the night
Wrapped in a blanket
But you told the lies
Hey, you choose it
Hey, abused it
Hey, refused it
Hey, you lose it
I cry and scream in the middle of the night
I can't go to sleep
I shake my head in the middle of the night
I can't go to sleep
It's not me, it's not you
