At the risk of touching things one is not supposed to say in this culture - wouldn't it be good to tone down that opprobrium, or at least cleanly separate out the things that are actually evil from things that are not? The connotational baggage carried by the term "eugenics" tend to infect serious discussions around genetic diseases and genetics in general, and people end up equating e.g. permanently curing genetic diseases (by removing them from the gene pool) with mass mutilation or murder of undesirable individuals (which is the evil part of the as-commonly-understood eugenics).
The opprobrium shouldn't attach to "eugenics", it should attach to "forced eugenics".
If some people are incapable of making the distinction, well, some people are incapable of making a distinction between male homosexuals and pedophiles, too. There's only so far we can carry an unfounded hatred of an extremely broad concept due to a tiny, distinguishable special case within that concept.
To see this in film, watch the Sid Davis classic "Boys Beware":
https://en.wikipedia.org/wiki/Boys_Beware
> The film equates homosexuals with child molesters and hebephiles, repeatedly describing homosexuality as a mental illness. True to the stereotypes of its time, the gay men in the film have mustaches, sunglasses and/or bow ties.

"heretic" and "science" or "monk" and "psychopathic torturer" are synonyms as well?
And it doesn't have to make sense to you. It's historical fact.
Would you call a black man "negro" today? It was a normal word back then. Good luck explaining the historical context.
There are plenty of historical facts which are just that :a historical fact with no connection to today.
It would not necessarily be an impossible stretching of the term, but as the vast, vast majority of people would not consider this a problematic solution it doesn't seem like it would really provide any advantage, and would run the risk of watering down the opprobrium attached to the term "eugenics" by including a thoroughly unobjectionable practice.
