I am an uneducated black man

To my sister, a loyal feminist:

I am an uneducated black man. I don't have the right to vote. People say the brains of black people are smaller than the brains of white people, and we are not as intelligent. Also we are not educated. Therefore it would be irresponsible to allow us to vote because we wouldn't be able to vote responsibly. We might vote for a tyrant, for example !

My sister says that although I am black and uneducated (she is white, educated and has the right to vote), she thinks that in my case I should be able to vote because she thinks I am intelligent enough. But she agrees, black people shouldn't be given the right to vote.
