It usually refers to people with genetic conditions. So it feels mean to them. Worse constantly associating bad things you don’t like with genetic conditions is like eugenics language. Further it isn’t actually descriptive or useful in discourse so it is intellectually lazy.
The normalizing eugenics language thing seems like a bit of a stretch I am sure. However, almost everyone here on this form started making jokes about comunism ironically. Then they got comfortable with it. Then they read some theory. It turns out our brains are really bad at keeping stuff out so you should make an effort not not say things that you don’t want to effect you. We don’t have free will. We are salty bags of goo. Brains don’t work as well as we’d like, mental hygiene is important.
It gets more complicated as this has happened with every use of the word. Fool, was a diagnosis. It referred to someone intellectually disabled back in the renesance days. Then it became an insult. Then we stop using it and forgot the context. Now it is a regular word. We can see people in this cycle with special and disabled currently.
Too based to be true
