James,
So if you neither trust the evidence nor can rely on a competent and honest professional to examine the evidence for you how do you decide? You end up making emotional commitments to positions based on subjective criteria that can not be falsified. That is what Mapes did when she and Dan Rather declared the story behind the Bush memos was true even if the evidence was false. You have simply inverted the process by declaring these theories false because you can not trust or evaluate the process by which the evidence is evaluated.

Global warming theory is not definitively proven or linked to the process you mention. That does not mean the process simply does not exist. Similarly it is not necessary to claim that schools do not teach useful information in order to support a claim that the current public education system is wasteful and should be changed or even abolished. Excessively strong claims about the evidence only serve to discredit an argument and hurt the actual policy goals you might be hoping for.
