I don't mean rejecting the mainstream view in favor of some existing contrarian position -- of which the majority are indeed unavoidably wrong, no matter what the merits of the mainstream view -- but merely applying the very basic tools of common sense and rational thinking to see if the justification for the mainstream view can stand up to scrutiny. My point is that often the mainstream view fails as soon as it's checked against the elementary laws of logic and the most basic and uncontroversial principles of sound epistemology. It really isn't hard.
