Its a deep seeded issue that permeates online game communities, but it is essentially born from the outside. We live in a society where everyone is told they are "special" and where realising your shortcomings is only something for the few. We all have shortcomings, and in their humility, ones who realise their imperfections learn to respect others.

In short - people are becoming dumber and online games are becoming more like a single-player experiences with online aspects, further fueling this issue. However, its unfortunate to say that you are part of the problem, because complaining on a forum only creates animosity. I'm really not sure what you were trying to achieve here.
