What, because I assume that people would rather have a life than hang around in limbo in a camp? Yes, yes I do. OTOH it's also completely besides the point as I'm describing, plain and simply, the difference between your "brown" and "white" immigrants. The difference is that they come from different conditions, not that they have different levels of melanin -- I mean seriously they often don't. You have yet to make even an inkling of an argument to the contrary.
