The tension between effectiveness (cohesive decisions swiftly implemented) and representation (complex reduction of utterly disparate points of view to a workable compromise) is the main force at the core of democracy.
Most of the electorate doesn't really understand it, constantly clamoring for one or the other to be the only guiding principle, but you need both - and one has to find a way even when they appear completely irreducible. Democracy is beautiful in a very messy way, a bit like nature.
