Imagine in the near SF future, new tech n' such, some sort of sanity test were devised... results might apply to all sorts of civil "permissions"--to own a gun, to vote, etc. I used to think about a so-called "humanity" test--might be surprising how many would fail. There are dystopic implications, of course.... who's to define "sanity"??? The Soviets declaring un-PC attitudes as mental illness, giving them the ability to put away dissidents in asylums, come to mind, of course... and I recall the story from a few years ago, some guy in the Denver area had a problem with his taxes supporting GLBT causes. Some hardcore lesbian was on the radio, she was really viscious about it--she declared that the taxpayer was insane and should be institutionalized. Could things come to that???
