Realistically because we have strong negative associations with anything to do with race. If people were changing the hair color of their kids for similar reasons, I doubt anyone would care. I don't think you can compare possible social benefits of skin color with very real benefits of loosing a major sense. How is denying them treatment functionally different than causing the condition itself? I remember a long time ago hearing about a cream which would turn your skin dark or even completely black, in the same way that tanning or genetics would do so. I.e. perfect sunblock. I haven't heard of it since, so it must not have made it to market, but I wonder if it would have drawn controversy.
