Biddies?
Be careful, man. A few months ago I used the word "harpies" -- not in reference to anyone in particular -- and one of them went absolutely ballistic on me. I just about needed a double-ankle-transplant after I finally pried the teeth out of my argyles! :)
It will start with pre-school children. In order to enroll your child in the local government training center (euphemistically termed "public school"), he or she will have to be evaluated by a government-licensed psychologist. Any child who does not fall within the parameters of whatever the State considers "normal" will be prescribed an "anti-psychotic" drug concocted The prescription will of course be mandatory; any parents who refuse to "medicate" their child will find themselves in the same position as the father in this news story who, after seeing his son's personality deteriorate under the effect of Ritalin, took his son off the poison and now may face prosecution--except that, in the near future, there won't be any "maybe" about it, parents will face prosecution, they will have their children taken away from them, and they will be imprisoned for defending their children.
That's how it will start. Then prisoners, whether they got into trouble for murder or burglary or marijuana possession or failure to pay a parking ticket or holding "politically incorrect" views or refusing to medicate their children, will be screened for mental illness. And they will be forcibly medicated, or implanted with a device to control their emotions. And the average, stupid American citizen will not care, because it's "only" being done to prisoners.
But then, one day, you will wake up and discover that you cannot get health insurance, a driver's license, government benefits, or a job, unless you submit to mental health screening. And they will test your "normality" with all manner of diabolical high-tech gadgetry. For instance, they will analyze your brain wave activity to discern whether or not you are lying when they ask you about your finances, your sex life, your favorite television shows, your political views, your religious beliefs, and so on. It will, of course, be junk science, with results subject to any sort of interpretation, but it won't matter--it will be the Law that you submit, and if you are deemed "abnormal" you will be medicated or micro-chipped, and you will be "cured.
