Someone would have to have to start defining ‘normal’ and frankly, with my work with children and my own kids, who are not neuro-typical, I think this whole idea should be put back in the Nazi Eugenics file it came out of. And no. We had this discussion somewhere where I had to link to several places to explain how we already lack in genetic diversity so much as to make out future existence perilous. Our human genome is so limited compared even to other primates and mammals, even, that it wouldn’t take much to whip us out as it is. Diversity in genetics is what helps species evolve to adapt. If we started wiping out mutations one at a time, we would be wiping ourselves out.
