Collective agreement is what liberates most groups of humans from perceived mental illness!
Consider some of the cultish groups!
Consider some historical tribal beliefs and practices!
Consider some present activists!
Dictatorships!
Genocide!
There is more proof than one can assimilate for such a notion!
Mental illness IS the individuals experiencing repeated INNER CONFLICTS reacting to the outer conflicts of collective others egos on a permanent relentless basis!
So YES = mental illness is quite often likely a purely artificial condition of permanent inner conflict, predisposed by a person feeling inedequate ( due insufficient self assertive thought networks) that they are so different from the group around them who perpetuate negative interactions with them in judging them for their differences.

God is in each life form though the collective whole is god and so god cannot be comprehended at any moment.
Or
Life is in each of us and the whole cannot be comprehended at any moment.
Respecting the life in EVERY form is mentally healthy!
Rejecting the life in any life form is mental illness!
Maybe more of us re than we realise = because we are considered by others egos (collective or whateve) to be so and/or we think we are?
