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.
With the added bit of not necessarily being accurate. Even if they do struggle with the condition, that doesn't mean their idea is bad. The idea being bad is what does.
