It's those semantics again, and of course you are correct in saying that there has to be a sense of normal or abnormal in scientific and linear type measurements, BUT the way in which the terminology is used by corberst is a human-value judgement --

Normal is what most everyone things (sic) is right.

When considering the human community that is so NOT what normal is. There are many deviations within the definition of normality. To think otherwise is to allow yourself to surrender to totalitarianism of the worst sort! Think about it--- you are different from me and my friend, so you are abnormal- so go away or I will hurt you--- or possibly worse-- hang around and I will patronise you.
