This is very tricky moral and philosophical ground. Sure, from a practical perspective most educated people believe the evidence that the holocaust did happen and Google ranking conspiracy sites highly in a way lended Google's credibility to those sites. The holocaust is a case I think most people can agree on. But isn't it kind of a dark road to go down to silence a dissenting opinion even if it is "crazy"? First this, then maybe people start demanding they down rank the global warming deniers and then before you know it a political party that is not in power, porn that is too weird, etc. Does Google really want to be the one that has to decide what the truth is? Then again, do we really want average people to be the ones to decide what the truth is? That's the simplest course but is not working that well right now. This is a tough question I don't think we have the answer to yet.
