Because she is.
She must be a thing.
Because she's brown.
She must be a thing.
Because she's black.
She must be a thing.
Because she was born a man.
She must be a thing.
Because she acts like a man.
She must be a thing.
Because she's a thing,
She is part of my dominion.
Because she's a thing,
She must be controlled.
Because she's a thing,
I will do what I want.
Because she's a thing,
What she is doesn't matter.
