True. But I might have a somewhat different take on this. Some quotes from the episode:We know from Dr. Bashir, I Presume, that genetic engineering can be used to fix "serious" birth defects. We can infer that does not include blindness..
I'd consider this a more telling tidbit than all the legal texts the heroes later quote. This is why genetic engineering is bad - it creates people who are "less human", and the other effects are subservient to this wider issue."..despite what the authorities would like us to believe, genetic engineering is nothing to be ashamed of. You're not any less human than anyone else."
When Bashir later laments his fate, he brings up specific points:
That doesn't necessarily mean that all genetic engineering is DNA resequencing (and therefore illegal), nor does it mean that genetic enhancements would be a showstopper outside Starfleet or the medical profession."DNA resequencing for any reason other than repairing serious birth defects is illegal. Any genetically enhanced human being is barred from serving in Starfleet or practising medicine."
We know there's legal genetic engineering out there, too: we see it in "Unnatural Selection". We don't know exactly where the limits are drawn, outside the specifics Bashir gave earlier. But we soon learn why the limits are drawn:"It was your father's suggestion, Doctor. He pleads guilty to illegal genetic engineering.."
So, GE can lead to people who are "less human", and mankind has bad memories of those. Apparently, Julian Bashirs aren't unwelcome - the process for creating them is, due to the risks involved." Two hundred years ago we tried to improve the species through DNA resequencing, and what did we get for our trouble? The Eugenics Wars. For every Julian Bashir that can be created, there's a Khan Singh waiting in the wings. A superhuman whose ambition and thirst for power have been enhanced along with his intellect. The law against genetic engineering provides a firewall against such men and it's my job to keep that firewall intact."
In conclusion, I see little evidence that the UFP would really take a dim view on "natal eugenics". Genetic engineering of humans and humanoids is being extensively researched in the 24th century, although under carefully controlled conditions, and people with "birth defects" aren't in obvious evidence. LaForge's happy with his cyborg vision (and turns down "normal" vision numerous times), just like Picard is happy with being bald, or certain extras are happy being obese or short or hideously ugly. Those things just aren't classified as defects any more!
(Picard isn't happy with having inherited Shalaft's syndrome, but apparently it was something UFP medicine could not screen against - yet could cure, once spotted.)
This might be considered an enlightened view in more than one sense. Perhaps a "serious birth defect" is narrowly defined as one that doesn't allow the person to survive till an age of independent decisionmaking. Blind people can stop being blind the moment they decide they want to - but some may decide otherwise, finding it vastly preferable to have cybervision. Taking that freedom of choice away from them by having doctors play with them before birth might be considered cruel...
