I would be all for selective breeding to raise the iq and try to weed out genetic diseases. Because all it takes is making sure people have kids with people who dont have the same diseases as the person you breeding with until its rolled out of the genetic code. So 3 or 4 generations down simple diseases like diabetes could be reduced, and cancer, hemophilia and who else knows what. But right now the only genetic breeding we get is when woman use sperm donors which is a shame.
