True, Psychotic Parrot, but now science is doing the same thing in reverse (hopefully with much less frequency than the selection you described).
I have multiple major medical problems with a high probability of being passed on to offspring. A gyn offered to help me have a baby anyway. At the time, I was also old enough where age-related birth defects would pose an additional risk. I don't consider that to be an ethical choice by either me or the gyn.
This is an emotionally-charged issue, no doubt.
Should scientists have absolute authority on who gets to breed? Probably not, IMHO. Yet I would like to see promotion of a new social norm that voluntarily changes behavior by raising awareness of overpopulation and ethics.
