some people here suffer from some complexes. That happens when somebody is afraid of his low qualities, he must then prove that there are worse people than him. Like Anglos, Jews, Asians, et cetera.

…and then there are also these people who randomly attack others for their views (of course they are even too cowardly to openly say who they are talking about) on internet-forums because they are pretty pathetic losers in real life or suffer from exaggerated self-importance.
