John,

I agree with you whole heartedly right up tot he last paragraph. These poeple are assessing their level of "eptitude" relative to a highly specialize4d subject. And moist specialized subvjects, rightly or no, do involve themselves with specialized nomenclature, the better to (a) pursue their specialty andf (b) create an insulated group of elite specialists. Anyone is qualified to call themselves a Dummy about X if it such a field and they have no starting knowledge of it.
