I notice a lot of people use terms like "psychotic" or "psychopath" as insults and negative descriptions on here. These are clinical terms that are used to describe real people with difficulties, not boogeymen! I don't disagree with the sentiment that these people are doing wrong, but if you wouldn't use the r-slur or "autistic" as an insult (which you shouldn't) then you shouldn't use these words either. And I get the idea of calling someone delusional, but take care that you don't just mean "I disagree with them." Though by posting on neurodiverse I imagine I'm preaching to the choir.
Sincerely, a casual schizoaffective disorder haver.
I do want to show some grace, though. Like, the language is so common and socially accepted that it can be hard to realize you're stigmatizing people. Though I agree people who double down would be problematic.
