Can there ever really be a black female protagonist

I know this isn't the usual crap I spurt about my life but I want to express something. 
Why is it that black female characters are either tragic helpless victims. Hateful vixens or a babies mama. Don't get me wrong there are many movies like the movie "something new" or "about last night." Even the Steve Harvey book based movie "think like a man." Where black women are actually portrayed as being desirable, fun, and quirky with Witt and a sense of humor.  But in supernatural dramas they are often stripped of femininity.  Like Hemlock grove for example and the only strong tough hard core black lady is a lesbian who treats the women she's with like trash, but the main love interest is the ethereal Letha Godfrey who is blonde, quiet, and white the ideal picture of flowery feminine bullshit.  Why is it that you can't be tough and be desirable without being a cold and humor less robot? Why can't you be soft and feminine without surrendering the ability to be strong.? Why does it seem like men can't write female characters without missing dimensions? It's like the character has enough to not be 2D but then they stop at 3D like oh well.
I'm so sick of stereotyping characters as well. A lesbian protagonist doesn't have to be manly or butch and treat women like a man does. And the protagonist of a heterosexual love story doesn't always have to be a glorified fucking saint.it seems like the same archetypes are used over and over again. Why can't there be interracial supernatural plots without them tiptoeing around black culture like it doesn't exist? Do you have to be completely white washed to be acceptable for an audience to love you? Because If that's the case we might as well still be reading Uncle Tom's fucking cabin! I'm a little pissed that writers can make multidimensional characters for pretty white women but the same stale roles are handed out to black actresses everyday. The wise black lady who is usually old and fat basically a mamie type figure. The sassy angry black woman who regardless of physical attractiveness is pushed aside because of her attitude.  And then the best friend.  Basically a sound board for white people's problems without really having anything better to do then make their lives easier.  Then there's the hard core bitch who is either hated in most of the movie, not to get any attention from men, and is stripped of being acknowledged as a female in general. This shit makes me upset. Smart People need to get their shit together and figure out a way to get outside of this shitty bubble without it just being a show on YouTube .
