As a neurodivergent person, let me just say that I have a great life. Why should you, or anyone else, get to make uninformed decisions about who gets to live based on inaccurate information?

Also, just look at bananas to see where eugenics ends up. Crops devastatingly vulnerable to disease, ans companies like Chiquita creating slaves of entire nations that manage them. It’s not hard to extend this wrt humans.

But really, the main reason is how tightly linked eugenics programs through history have been linked to fascism.
