Broadcasting a World of WHiteness

The article " broadcasting a world of whiteness" has to do with television shows producing shows with specific groups of people, mostly white or mostly black.  this article expresses that there should be more shows with a diverse cast.  The article gives an example of a show without a diverse cast, HBO series girls has an all white female cast.  This artle is just another article by someone being overly sensitive.  Not all shows have to be to your likeing apparently if its still on air somebody watches it.  I watch jersey shore and that show has a all white cast.  So as you can see its not about race its about shows that are to your likeing.  I also doubt producers think about racism during casting, its about whos good enough to be apart of the show.
I also should point out that the article says, "Whiteness is too ofter invisible on television, so much the so that this fact is hardly ever pointed out, and for whatever advances "girls" make in expanding the range of women on television, and the sorts of conversation they're permitted to have, it certainly lacks for other forms of diversity."  This is true but also so unintelligently wrong.  people know what they are watching but their is lack of diversity but it is okay as i have pionted out why above.
