I hate to say it, but maybe some groups of people need the shared experience of war to find common ground with each other enough to sit down and talk. Before that, they perceive they have nothing in common and treat people as “other.”
The perception of “other” being specifically programmed by various leaderships through propaganda and population conditioning is a separate but related issue.
I mean, there’s other kinds of public mental health institutions than full inpatient.
Why not have, say, a location with publicly-reimbursed psychiatrists and psychologists, where a person goes for an appointment?
