Agreement, particularly with your statement about nanotech sex-changes
finally wiping out the problem. I had much the same idea about wiping
out racism with melanin blockers/enhancers, except that I didn't think
it would require nanotechnology. In any case, I first thought that if
you could decide what color to be today by gulping a couple of pills, it
would solve the problem. Now I think it would only ameliorate it; you
could probably still distinguish between races even if the colors were
random.
