This one's a LOT easier.
By post no. 2 the poster has DEFINITELY begun to try FAR too hard, given that the profound truth that he claims we need "Basque philosopher Miguel de Unamuno" to enlighten us about boils down, in essence, pretty much to:
"Sex is fun. But falling in love with someone and making a commitment to them can be less so."
I don't think we really need to go to Bilbao and wade through eighteen volumes of existentialism to grasp THAT point. Any divorcée in Weston-Super-Mare will be able to explain it to you without the aid of Kierkegaard quotations.
Actually, on consideration, I'll revise that. The OP is trying far too hard already at post no. 1., when he starts talking about people "failing to grasp how truly appropriate" the application of a certain word was.
"Trying too hard" is always a major risk on a board like this in this particular (linguistic) connection, as the OP is representative of most of the rest of you in knowing a great deal about computers and NEXT TO NOTHING about anything else, least of all about words and phrases and how they are "appropriately" or "inappropriately" employed.
Admittedly, with his "failing to grasp how truly appropriate" bullshit he's only being condescending to OTHER semi-illiterate computer programmers.
But it so happens that, in this case, it's the computer programmers who are right and this pretentious idiot who has gotten it wrong.
The association of "sanity" specifically with the state of good MENTAL order - and, correlatively, of "insanity" specifically with the state of MENTAL disorder - is a mere connotation that the term has acquired (above all in colloquial English; the cognate terms in French or Italian, for example, bear no so exclusively mental a connotation). The word's DENOTATION is no more than the "healthy condition" which is given as the term's definition by the Oxford English Dictionary.
The programmers whom the OP refers to, then, have not at all "failed to grasp" the appropriateness of their use of the term "sanity" in this case. It's rather the OP himself who has "failed to grasp" the linguistic issue here, "trying too hard" as he is to show how much cleverer he is than everyone else.
