The problem is not so subjectively limited as to be a right-wing problem. Communities, unless extremely well policed, tend to become gravities of like mindedness when there is a visible vote system. This seems to occur because vote counts, whether positive or negative, are viewed as a form of credibility and because people are generally hostile to disruption and originality.

When you step back from a subjective slant the phenomenon of group think has been well studied.
