Simply put ... in an amoral world we would sterilize or euthanize everyone that does not meet some criteria developed by those self-annointed moral authorities such as politicians and priests.

Of course doing so posits that they would be willing, for what amounts to purely financial purposes, to define the end-point of human evolution and progress.

The rest of us, having taken a close look at the Nazi experiment, might decide it is worth living in a world with imperfect people to protect ourselves and our families just as those that love freedom of speech tolerate those with whom we disagree or find obscene.

The cure, as demonstrated by human history, is far worse than the disease.
