Who is she? She's an author?

Why are some writers not given the due they are deserved? Not to sound like a raving lunatic, but it seems like women of color are definitely not given the attention they deserve. Why is there even an African-American section in the bookstores? Are stories written by African-Americans considered not main-stream? When you are a female and a person of color, it seems like the publishing industry want to put a label on you, as if you fit a type. I know there are some great Black female writers that I will never read because they aren't promoted:their books aren't displayed in the front tables of Barnes and Nobles, their books don't appear in the fiction section. Instead of placing writers' work in racial categories, how about we place writing in the following categories: nice try, average, good, and excellent. Maybe I'm getting carried away, but it is food for thought. Any opinions?
