"To repeat one thing endlessly, to dwell on one theme at great length. To tell the same tale over and over again. If a harpist were to play her instrument upon one note, the monotony would drive her nuts if some unwilling lestener had not already killed her."
That comment does not attack any person - but it does point out some behaviour which drenches this site.
I started a thread recently on the need to win. Again, it wasn't targeted at a particular person - there were a few of us being highly focussed about winning arguments, to the point of making negative comments about other catters.
In an open forum, destructive behaviour, whether its obsessive repetition, victimhood or nagging, effects the site. Comments on behaviour, ideas, methods of communication are constructive - anyone can think about.
