Your clearly suffering from cognitive dissonance if you cannot fathom how eugenics conveniently happens to parallel all the selective breeding and previous "race science"(pseudoscientific nonsense) and how it impacted future extensions and "research". The history is ugly and most wont talk about it, its purposely buried as a historical blemish, just like the rapist founding fathers dentures were made from slave teeth. They needed a dentist to build those dentures or doctor of some sort, whatever rudimentary knowledge was expanded upon or completely overhauled at certain historical points do to scientific advancements, every single medical "science" at the time did this to some degree when considering slaves were the first "products" this was "humanely" tested upon.
Do you believe white privilege exists? I'm more curious if any mental labor with you is even worth the effort.
