The key point to remember is that Wikiepedia's goal is "verifiability, not truth". With that one fact they neatly sidestep a lot of the arguments from cranks and whatnot about including this or that fringe view out of a commitment to "truth". Truth isn't their goal: Wikipedia is meant to be an accumulation of best-guess knowledge at the current time. It may seem like a lower goal, but that's all any encyclopedia was ever supposed to be.
