the "internet gaming community". Key word here being "internet".
It actually all feeds into what I would call "internet culture". Its a sensationalist culture. one that feels everything has to be exaggerated to have an impact. Little things are made big and big things are made epic.
This is why doom or bad topics are more popular on the internet. Its also why people feel the need to be abusive or insulting to others. Its not about being anonymous, its just all an inherent need to be noticed or acknowledged.
