I spent a year in the 1980s working as a psychiatrist participating in the admissions rota where I would cover all the medical work necessary in a large hospital overnight or at weekends.
Quite a few of the patients were brought in by the police, by ordinary police officers - who had been called to some incident and recognized that the person involved was 'mad not bad', and so brought them in for psychiatric evaluation instead of putting them into the cells.
The police were never wrong, in my experience. The people they brought in were always crazy - it was just a matter of sorting out what kind of crazy. In other words, an ordinary policeman was able to tell when somebody was insane - it was a matter of common sense (plus relevant experience).
But now? Craziness is built-in, high status, a marker of 'goodness' - increasingly compulsory.
It is hopeless to try and explain why crazy things are crazy - if they really are crazy, then everyone knows. But apparently everyone does not know - there is a bland acceptance of the insanities of political correctness which means that we are in the position of trying to explain, argue, prove that something obviously crazy really is insane...
Of course, this is characteristic of dealing with insane people - they have no insight. That is the nature of insanity - akin to nightmares in which we accept whatever extreme craziness and illogic the dream brings, after a the merest brief twinge of puzzlement.
Indeed, such is the extremity of the situation, that the insane people label normality as crazy. And here is a clue....
The situation has arisen and continues because in the modern West normal people are impaired. They are indeed so impaired that they cannot do what every policeman used to be able to do - which is to recognize crazy.
What is the cause of modern impairment? Well, I have argued two main causes on this blog: genetic damage - population wide mutation accumulation over the past several generations (i.e. the posts labelled 'mouse utopia'). That means that nearly everybody is ill, and lacks spontaneous instincts which used to be taken for granted. People accept insanity because they are too sick to notice or be bothered.
On top of this is secularism: the atheist assumptions of all significant public discourse in the West: the assumption that there is no God, no soul, no afterlife, no supersensible realm - no transcendental purpose, no objective universal meaning to life... and the rest of it.
The developed world is itself insane because it has deleted religion; and Man without religion is insane.
Religion (of some kind) is natural, spontaneous, built-in. All societies everywhere have always been religious (a tiny minority of atheists make no difference) - life without religion is new, uncharted territory for humans. But now a whole public world and discourse of religious understandings, interpretations, explanations - religiously framed laws - religious reasons for significant actions of the state and of individuals etc... utterly gone.
The insanity of Man without religion was not immediately obvious, because the generations overlapped, and for many decades people were brought-up on a religious basis, and only abandoned religion in adulthood. But there was a tipping point evident in the mid-1960s, and now for fifty years (two generations) the West has been ever-more-completely functionally atheist (especially considering that most mainstream self-identified Christians have such a feeble faith that it makes zero observable difference in any way; not even to the litmus test issues of sexuality).
My overall impression is that although Modern Man is genetically impaired such that his instincts are weakened and deranged; even this is not sufficient to make him lose his basic orientation and discernment when religion is strong.
A strong religious society is, substantially, antidote to the behavioural impairments of mouse utopia.
This can be seen in the most profound marker of modern decline: the sub-replacement fertility universal in the entire developed world (less than two children per average women, usually much less when new immigrants are excluded) - this is (obviously!) a short path to irreversible decline and extinction.
Yet serious religion is indeed an effective antidote to sub-fertility - even among the very craziest sub-populations (i.e. the intellectual elites).
So - when confronted by the normal everyday experience of trying to explain to insane people why something insane really is insane... take a step back. Remember that it is the basic metaphysical framework which is wrong - it is the deletion of religion from life which is crucial.
Man must have religion and there is no arguing with 'must'.
Legitimate and constructive discussion is merely concerned with the choice of which religion.
