Frank. There's quite a difference between a psychotic who goes on a shooting rampage killing many people.....
But good sir, please notice I made that distinction, saying "let's keep autism itself out of the discussion."
There are, obviously, people in this world whose anti-social disorders can't be moderated despite the expenditure of massive blood and sweat of the taxpayers.
The care and treatment of the autistic is probably a better "societal investment" than the subway cat, for example, or the phalloscraping primitive.
So autism isn't in my question at all.
My thoughts are that the reedy tom primitive brought up a good point; what are we to do with the incurables, the psychopaths and sociopaths and people who imagine themselves felines? How much money, time, and trouble should we spend on them?
Increasingly, it looks as if we can afford to spend less and less, to where the only solution seems to be shoving them in front of a speeding bus on the highway.
