Race/Gender: Who opresses Who?

What does gender have to do with race? Gender creates race because America is based on a hierarchy. For example, a white male is over a black male; a black male is over a white woman; a white woman is over a black woman. Black women are at the bottom of the hierarchy, so why is that one black woman is the example of all black women?Why is that black women feel that they would better off dancing in a video rather than stay in school and get a degree?  IN my opinion, black women are exploited by society and by themselves. They feel they are taking back their bodies and in doing so they feel that have to look and maybe be sexual animals. They have not had someone who respected them or cared for them enough to say that is not cool and you should not do that. People don't realize that they are the depiction of the rest of your family. if do something horrible then society is going to look at your parents, grandparents, aunts and uncles. They are going to look at how they raised you and how they influenced your life. However, maybe the quickest way out of their community is through a video and they feel their is no other way. Many primarily black communities don't see black lawyers, black doctors, black senators, etc. They don't see prominent black affluent families in one neighborhood so they take other routes such as dancing in a video. So my question is Who is the forcing mechanism who oppress women? Is it women them selves or society?
