Two-party system

One theory is that neutral point of view is really a systemic bias (in large public wikis, an editorial bias). This is resisted by a New Troll point of view that refers to it as groupthink or just bogus or a product of individual biases.

As Trolls gain rights and force sysop power structure to adhere to some social contract, a two-party system develops. Formal factions in and out of these two parties jockey for control of the consensus and the dissensus. Eventually, a true multiple point of view system evolves.

See w:two-party system for historical examples of this in politics.
