The fuck it isn't

To the people that only know eugenics as "the thing Nazis believed", then it is. The way neonazis onboard people is by asking questions such as "don't you think we should try to eliminate this horrible genetic disease?"

It's the same premise.

Edit: actually, I had forgotten. The pseudoscientist inventor of eugenics, Francis Galton, specifically sought to make the human population smarter.
