Humans tend to form groups that disagree with each other. This is a biologic feature, not a bug. From a multilevel selection perspective, evolution selects for systems with features that increase evolutionary capacity: imperfect replication, sexual reproduction, predation, programmed death, and memetics. Add to this list memetic parallax, the tendency of meme groups to diverge into competing views.
