Most of this argument is based on the idea that some expert automatically makes an article more accurate. This just isn't the case. An article on physics isn't more accurate just because some physics professor said it was. Its more accurate because it has valid arguments and has references that support its contentions. Carl Sagan, (and I understand the irony of citing an expert to invalidate the idea of experts) called this type of argument "argument from authority" and included it in his baloney detection kit. No one is above having to explain their reasoning. This ability to do so is in fact what defines an expert.
