Where do you encounter something like this? Could you point it out to me? If it deserves such a ridiculous rebuttal I would expect to be able to easily find it online.
I don't keep a log of silly eugenics nonsense I encounter and, if nothing else, we probably have the common experience of Google getting worse at this kind of query. Some of it was on HN, at least. If you find it, good luck! I've never had much success rebutting this kind of thing.
