Mental health is real, but I think some conditions, like trannyism and violent schizophrenics are 100% demons being misdiagnosed as mental illness. And demons can probably cause mental illness (and a whole host of other diseases) without actively possessing someone, but the conditions can also occur naturally. The big thing the jews have done is completely ignore the spiritual component (or more accurately, convince people the demons they serve arent real), while also declaring some *severe* mental illness, like faggotry, is perfectly "normal".
