Most of the black oscar winners in this 2000-2014 era won their oscar playing a slave, maid or the main character of a biopic.
Maybe you want to rethink this and add some more selections because during that timeline you provided only one person has won for a role of a maid and only one has won for a role as a slave. So, um, I guess all the others are biopics? Oh, wait.
Between 2001 and 2014 the winners have been:
Denzel as a corrupt cop
Halle Berry as a damaged widow
Forest Whiatker as an African dictator
Jennifer Hudson for a singer in a female group
Monique as a ruthless, abusive mother
Jamie Foxx for his role as a famous music icon
Morgan Freeman as a boxing trainer
Octavia Spencer for a maid
Lupita Nyong'o as a slave
Do the math. Even if we combined the biopics with the maid and the slave that would only be FOUR of the nine winners, which shoots down the theory that MOST of the winners came from those three categories. Sorry to ruin your argument with such annoying details known as facts. Actually I would even argue that Whitaker didn't even win for a biopic since that movie was all about the fictional white doctor not Idi Amin.
Look, I too realize there is a lack of variety in roles black people play. Been talking about that for years on this board. But let's not make bullshit up to prove a point. The reality is that slavery has not even come close to being addressed as often as it should have been. Same thing goes for the civil rights movement, one of the greatest moments in the history of America. Films about these subjects were not made because studios didn't want to insult or alienate white audiences. But here you folks are justifying the neglect of these events on cinema by basically siding with those who wanted to stay away from the subjects because they thought they were too racially charged. And what is your excuse for doing so? You are too ashamed of what your ancestors and predecessors had to go through? Fuck their pain of being forced to work in cotton fields, that ain't nothing compared to the trauma you guys have to endure by seeing black people in servitude on the big screen as you rest back in your comfortable movie seat while chewing down popcorn. The horror.
Once again...in the history of Hollywood there have been about a half dozen feature films that put American slavery in the forefront. Meanwhile there are a half dozen horrible black rom coms and a half dozen Kevin Hart flicks EVERY year.
