How's abouts this my friend, why don't we just settle for a mixed bag of colours and ban ALLreligions therefore we'd all need to become atheists, God(s) forbid!
Love your theory but it ain’t ever going to happen, so dream on!
Isn’t there a secret society, hoping to interbreed all the racial groups and have humans of one particular colour?
Even if this conspiracy group are successful; humans will find some excuse to form clans or tribes to fight over something.
The only way I ever seeing your theory coming to fruition is if we ever have conflict with some aliens, as portrayed in movies such as Star Wars etc.
