As I said in an earlier comment...if those things count as eugenics, then all personal choices count as eugenics. The only thing that wouldn't, is to accept a purely random outcome with no conditions at all. Meaning, you don't even choose your partner based on looks, or intelligence, or background.

Any selection based on personal characteristics would be considered eugenics. And that's simply ridiculous.

I chose my wife because I thought she would make a good mother. She was kind, patient and gentle, with a great sense of humor. All qualities I admire and respect. Do I want my child to have those qualities, as well? Sure. Is that eugenics? No. It's just selection based on the attributes you consider favorable.

If you want what's "best for your children"...you choose your partners carefully. You aren't engineering future populations. You're just being selective about who you choose to share yours with.
