Child molesters, especially “sexually violent predators.” The vast majority of sexual offenders are borderline date rapists and incest offenders, meaning that the vast bulk of sex offending is both widespread and undetected. Around 1996, various legislatures around the US invented the legal category of “sexually violent predator” in order to drum up and to capitalize on people’s fears and hatred of sex offenders in order to provide occasions for politicians to show how tough they are on this pariah class. In California, there is one registered sex offender for every 186 men. I have no doubt that if the true range of sex offending were known, it could very likely be 1 in 18.6 or maybe even 1 in 5 if you count men who persisted even after the woman said she didn’t want to continue.
“Criminals” and anyone who has ever been to prison. Roughly 87.5% of the people in prison are there either on drug or drug-related offenses, because they are mentally ill, or because they are parolees “violated” for technical conditions of parole (things that are not actually crimes).
Drug addiction, particularly heroin, meth, and crack. One would think that addiction was a fate worse than death. In actual fact people get addicted to sugar, fat, caffeine, alcohol, and nicotine (the most addictive substance of all) all the time without becoming demoralized or unscrupulous. At one time both heroin and cocaine were sold over the counter and people had little problem with them because doses were low and easily withdrawn from. Meth was supplied to millions of men on both sides during WW II, Vietnam, the Gulf War, and to millions of housewives, with few ill effects. Cocaine and Ritalin are chemically almost identical, yet we demonize one with punishments approaching those for homicide, and we give the other to our kids, sometimes whether they need it or not. Most of these fears are artificial—that is to say, they are ginned up by propaganda and yellow journalism, often with a racist tilt. It turns out there was no such thing as a “crack baby”; these were simply preemies born to poor black women. The fact is, anyone who truly wants to quit can simply decide to do so; indeed, about 5% of all addicts quit on their own and stay quit, if left alone. Making drugs illegal only adds a layer of complication, obsession and dysfunction that makes it difficult for the addiction cycle to run its course.
Cancer.
And, for certain people already predisposed to irrational panic: Witches, sin, damnation, the end of the world, and anyone whose “wickedness” might call down God’s Wrath on the rest of humanity.
