I'm not sure if this belongs in the Whine and cheese board or not.
It seems to me, wherever one goes, weather it be an education establishment, a job, or a simple forum, you always and unavoidably find two types of person.
The first is the "In" crowd, the clique of people who have grown comfortable with whatever establishment or group they are part of. The kind of people who have been there for so long, they are practically part of the decor. The kind, that can almost be frightened by new arrivals, who may feel that their position is threatened by it. The kind, that eventually come to believe they hold the patents on said group or establishment. Examples of these, from my own experiences, would be the groups of supervisors in jobs such as markets, shops, restaurants, etc. The popular crowds in school. The opinionated windbags of most popular forums (and parliaments).
The second group, is a bit harder to label. These are the layabouts that have nothing better to do than to poke and prod, and find things to complain about. These are the kind of people that, for whatever reason, feel insecure in most of life's ventures, who's only means of assuring their position and self-worth is to find something to attack, something they can rank below themselves. These are the forum trolls, the workplace shit-disturbers, the politically correct gestapo, and to a less serious degree, the grammar police.
Even though both groups are at extremes, they have a few things in common : over-assertiveness, the inability or unwillingness to leave ordinary people alone (annoyance), and the undying will to have others see things from their point of view (righteousness).
So, is it human nature, or human fallacy, that we will always encounter both types wherever we go? Whatever happened to "Live and let live" ? Where does it leave the rest of us who don't always feel the need to be part of, or create, conflicts?
BTW, I'm quite aware of the irony of complaining about complainers, so no need to point that out
