On the other hand I could call myself an "intelligent design advocate" because (a) I think it would be great if things were designed intelligently, (b) I am intelligent and I advocate designing stuff, even do a bit of my own, or (c) maybe I really mean that humans—geneticists, even—should more thoroughly assume this "intelligent designer" role, pulling the right strings to cheat natural selection.
Problem is, promoting the traits favorable to said designer over those of the fittest would amount to eugenics, so obviously don't tell people I advocate that. But I guess if I were some kind of deity doing the same shit whilst being worshiped by them it would be acceptable.
As has been noted, the words "eugenics" and "intelligent design" both have connotations that make them unusuable, however apt they may be for some purpose.
Today we call eugenics "genetic counselling" when we're trying to eliminate negative traits (Tay Sachs and cystic fibrosis), and we don't even have a name for it on the positive side, though it's implicit in mate-selection (actually I think we call it "eharmony", "hotness", and "eligability").
Darwin knew that sexual selection and artificial selection both work much faster than standard garden variety environmental natural selection, because the element of "designed mating" puts far more pressure on the system than other types of environments. Human mating is simply a hyperdriven cross between artificial and sexual selection; we have always been at least as interested in breeding ourselves as our domesticated crops and livestock, and look what we've done with THOSE over just the few thousand years of recorded history! The various human races are no doubt a result of vigroous self-selection, just as much as dog breeds, cat breeds, and crop varieties. This sort of thing descreases diversity on a small scale, but increases it on a large scale. Are dogs less diverse than wolves? Any given breed is, but the entire collection is more diverse. That's how evolution WORKS.
HK's comment about it being "bestial" to locate human identity in biological or racial traits, is very odd, as it's clear that our identity as a species is partly in our culture, and partly not. You can't turn a chimp into a human no matter how you raise it (this has been tried). You can see this in other animals that have been domesticated: you'll never ride an African elephant, no matter how well you train it, or how young you start. But with an Indian elephant this is a possiblity. Similarly, it's possible to ride a zebra if you start very early and are very lucky, but breaking a wild zebra is totally impossible-- there's no comparison with breaking an adult mustang horse, which has the genes to be broken for the saddle, just as the Asian elephant does. To imagine that humans don't have as many "domestication" genes as dogs, cows, and Indian elephants is very, very naive.
