How do you know they're not?
Wasn't there just a special called "dark girls"? And now a group of dark skin little black girls are receiving something that doesn't represent them and in fact represents what most will ridicule them for not being yet it's ok because it's just dolls?
Thing is, these are African girls. They aren't Western girls, their standard of beauty probably isn't swayed by something like that. Even so, they're children who just see them as toys and nothing else.
My favorite toy as a kid was a pale faced Dracula. I didn't need Blacula to see myself represented because that was the furthest thing from my mind.
And judging by the looks of those dolls, they wouldn't be representative of those little girls anyway.
