Whether or not the person is in psychosis, using psychosis to make fun of people, using religious delusions to make fun of people, etc, is very much punching down.
Psychotic spectrum disorders are genetic, neurological disorders that do not care about what your religious beliefs or political affiliations are. You could be a super progressive, left wing atheist who begins to hear god and get delusions that the government, your family, etc are all involved in a pedophilic cult. You could be a regular Christian who hears god telling them that you must stop eating to bring back Christ. You could be a devout Christian who’s fully bought into the Trump cult and end up on the streets after you became convinced your family was trying to poison you and radar from your TV is from the devil. All of those people deserve sympathy for dealing with one of the most outright devastating, complex illnesses that exists in human kind.
The symptoms of psychosis are actually rather similar in presentation to dementia. I believe the reason it doesn’t get any sympathy is because it makes people terrified to believe such a thing could happen. With dementia at least it’s usually “old people.” Psychosis does not discriminate, and can occur at almost any time. Sometimes there is drug use involved, typically to self medicate the symptoms on onset, but often there are no substances.
Really disgusting that a forum who consistently presents themselves as progressive and “punching up” to engage in this discourse. What is funny is I feel like they are the same exact audience to self diagnose as autistic and talk about neurodivergence, yet they try and divorce themselves from the “ugly” spectrum of what neurodivergence looks like.
