>Post-human doesn't imply eugenics.

There's a lot of overlap.

>Eugenics is about breeding a "superior" race and the eradication of "undesirable traits".

I mean, I can afford to give my kids a lot of advantages. In ten years that might amount to some nifty germline edits for every one of my descendants going forward. Project that advantage into the future...

If people don't want to use my tax money to subsidize these for everyone else's kids, that's their choice.

>It necessarily implies an authority defining what traits are desirable for a large group of people (the "race" in question).

It's called the FDA. As much as I hate them, this is literally their job.

>It goes beyond breeding and race and the need to eradicate any specific trait.

Some traits need eradicating. It doesn't have to be controversial; just allow parents choice and subsidize the costs where reasonable. This is hardly unprecedented, even with touchy issues. Look at the abortion rates for fetuses with Down's syndrome.
