Moving parts in rubbing contact require lubrication to avoid excessive wear. Honorifics and formal politeness provide lubrication where people rub together. Often the very young, the untravelled, the naive, the sophisticated deplore these formalities as 'empty,' 'meaningless,' or 'dishonest,' and scorn to use them. No matter how 'pure' their motives, they thereby throw sand into machinery that does not work too well at best.
Robert A. HeinleinThe faith in which I was brought up assured me that I was better than other people; I was saved, they were damned.... Our hymns were loaded with arrogance - self-congratulation on how cozy we were with the Almighty and what a high opinion he had of us, what hell everybody else would catch come Judgment Day.
