@Eden1919 @Willy I think that part of the problem is that there's no doubt a large gap between the official textbook definition of "psychosis", and what the average person on the street is likely to call "psychotic" behavior.
Regarding the prejudice against people with psychosis... It's a complicated issue, because there are two sides to the story. Yes, people with psychosis understandably want their freedom and to be treated well and respectfully. But non-psychosis people want to feel not only safe, but also connected to their community; they want their neighborhoods to be their home. The more you flood those places with incomprehensible alien mindsets, the less and less of a home they will have.
There is also a level of compassion for the victims of (apparently rare) psychotic assault, and a yearning to view such tragedies as lessons that have been hard learned, and which action will be taken to insure they don't happen again.
I can't help but think of the story of a certain famous actress - I'll call her Cauley Cerrette (😉). She got attacked and injured by a psychotic homeless guy, for no reason, several years ago. Fortunately for her, a cop just happened to be in the vicinity and detained the guy before he could do too much dammage to Cauley.
She hailed him (the cop) as her personal hero and sung his praises all over the internet.
A couple years later, the same hero cop, walking the same beat, got ambushed by the same psychotic homeless guy. This time, the cop got messed up really bad.
As you can imagine, Cauley Cerrette was outraged. Why hadn't the lesson been learned? Why hadn't anyone taken notice that this guy was a menace to society, when he had clearly demonstrated himself as such? Why hadn't steps been taken to insure he couldn't harm any more innocents? A good cop lay in hospital, seriously injured, as a result of the failure to learn those very basic lessons. But instead, a tunnel-vision focus upon appeasing the minority of people with psychosis has left that community with a revolving-door system that turned the guy loose in a jiffy.
You can understand the anguish from people who care about that cop. "What can we do to insure this never happens again?" They fairly cry out.
Is our answer to be: "Sorry, there's nothing that can be done. The contentment of psychotic people is most important. Your literal safety, and sense of safety is secondary. You just have to politely tollerate the fact that your community now has a mildly elevated risk of harboring a potentially dangerous person."?
I'm not suggesting it's fair for the entire psychotic community to have to pay for the misdeeds of a slim minority, such as the man mentioned above. Certainly, the vast majority of them are harmless. I'm just saying that the concerns of so-called regular people are not unreasonable, and shouldn't be lightly dismissed as irrellevant, or baseless.
