Good and thought-provoking call, dear Tess. Indeed, it does not help people with psychiatric disorders at all, if they are being addressed with derogatory terms. However, what should we think, then, of TV comedy where a normal person who acted foolishly is named in such a way? And where should we draw the line? Think of the word 'mad', as in: the mad scientist. Or: 'instable'.
Now, I am totally with you in a hypothetical case of a patient with a mental disorder, who is called a 'nutcase', or 'bonkers'. Which automatically would apply to Moammar al Khadafi being named a nutcase - the man very obviously suffered from some form of psychosis, with severe delusions of grandeur. He could only 'lead' his country for 42 years with extreme violence, torture, and murder. That speaks volumes about his psychiatric condition. Roughly the same goes for Saddam Hussein. Calling those persons nutcases on public television isn't necessary at all - we already knew their illnesses to be the case.
Apart from these two examples: most people with mental problems are modest, shy folks. The public at large (including many without a proper education and/or common decency) often knows very well whom to insult, i.e. the most easy prey it can detect on instinct. People unfortunately have mean and indirect ways to vent their own problems (hidden anger, jealousy, frustration); and insulting those with a psychiatric disorder is such a way - the response is mostly weak or absent. Patients can't correct their detractors all of the time, if they can at all.
So what's to do? I think that a good start would be to correct those in our immediate vicinity who overstep the line of decency. Furthermore, we might send e-mails to broadcasters who go too far from our perspective.
Oh, and before I forget: I truly detest the (mostly American) motion pictures in which not a single line gets spoken without (multiple) use of the f-word. I never could get used to this phenomenon, and never will either. It is such a gutter thing... and perhaps it betrays the total inability of the scriptwriters to come up with a good dialogue. Perhaps this cultural relativism is a sign of what's wrong with Western societies... where one cannot see too much difference any more between a CEO of a bank, and a robber.
Ciao, Cuthbert.
PS: to make insults towards patients anathema might pave the way for treating them better, i.e. respecting their situation, and helping them with funding and materials to improve their condition. Changing the verbal approach is all well and good, but I just thought of the Indians in the U.S. - they got called 'Native Americans' at one point, and now it's 'First Nation Americans', but as far as I know, many of them still live in miserable circumstances...
