*Why does it matter if storm or Uhura is light-skinned or dark-skinned they are still black plus its about the acting not their skin tone.  Halle Berry is biracial and Zoe Saldana is  Dominican and Puerto Rican but they are good actors.*

I was aware of their ethnicity already.  And yes they are both good actors and beautiful women (although Zoe's thinness is approaching gross levels).  Why it matters is the same reason Loreal airbrushed Beyonce's skin lighter in her ads in 2005.  It's the same reason Elle Magazine lightened Gabourey Sidibe's face by like 5 shades on their magazine's cover last year.... Dark skinned black women are not considered attractive or desirable in the entertainment business and it has an effect on the rest of society.  And with Storm and Uhura, you have two characters who would normally be dark skinned women, played by lighter skinned ones.  It's like M. Night replacing the obviously asian main character in the Last Airbender with caucation kids.  As for the negative effect this has, ANY psychological study done with children regarding race will show it.  )Hell, I'm a victim of it myself.  I'm a dark skinned black woman and it took me years to realize that I could be considered beautiful, and didn't have to use all those skin lightening creams.)
