Things like the debate over global warming are purged, and Wikipedia presents one side of an argument as 'consensus'.  What Wikipedia's insistence on 'consensus' means is that only one view will ever be presented and the most aggressive group purges all dissent.  And the most aggressive group over there is an authoritarian left-wing - that hates sound money.  Knowledge is power and their goal is to limit and shape everyone else's.  NPOV is of course totally Orwellian, they've simply declared their POV as 'neutral'.
