Alright, I made reference to stigma because of what I thought "Most of it I think was that his "cuteness" as a child allowed caregivers to respond his behavioral/physical problems with some sympathy instead of "ugh, get me out of here" implied. Upon further reflection it's not entirely a stigma issue per se anyway, but perceptions inevitably play a part, as they do in every such issue.
I've been keeping the personhood aspect of this case on the backburner as I haven't looked any further than the original article, but assuming that she has none then most any objections along these lines are moot anyway. I however did think that whilst the law can be changed, the procedures undertaken here are irreversible, so I nonetheless still make a distinction, however slight (and inconsequential) that might be.
We could probably make a more detailed thread specifically on eugenics later, but for now, my concerns are not so much about the value-laden racial bias, but along a more recent trend of exploration typified by experiments on homosexual rams (the agenda allegedly being to find causation and therefore cure). Without wading in too far just yet, I do think some fine lines have to be drawn between balancing fixing the disability effect from some genetic conditions and a generalised institution of eugenics as the latter will simply tend to incest (it has a negative impact on genetic variability and thus species survivability).
For starters, where the condition would make it largely impossible (from a primarily biological standpoint) to reproduce, then it would be reasonable to take into account other factors and implement screening processes. But as of present this remains a huge ethically grey area.
