Believe me, I'm not trying to convince a Scientologist

Just suggesting that it's this acceptance of tendentious and flawed concepts and taxonomies that *makes* a person a Scientologist.
If you want to say that 'Case' is a *description* of a set of qualities or attributes, I'll go along with the gag and agree that there is a 'Case' as a *description*. A particularly hinky and tendentious and truncated description of the marvelously broad and marvelous human condition, but, still, there is a 'Case'.
To take it out of the clammy arena, I have some of the same objections to the term 'meme', which, as a metaphor for the viral transmission of information has some value. But, once you start treating 'memes' as things floating around in the physical atmosphere it's time to find the butterfly net.
