A problem is that some see 2 as a subset of 1, upset at the idea that parents would wish to terminate pregnancies early that have strong indications of defects. I do imagine a good chunk of those people are of the horribly broken belief that abortions should be outlawed altogether, so not sure how many specifically go against such "filtering".

Granted, if everyone were sequenced and had access to that information it probably wouldn't take too long before certain categorizations became a requirement on the dating profiles, and that's a slippery slope...

(Regardless, nature filters us all by genetics in several stages, and our entire concept of sexual attraction and social groupings are based on the most direct form of priliminary selection for genetics that evolution could achieve with our limited available senses.)
