you honestly don't see a difference between something that is backed up by "well that's what we believe" and "I have compiled statistics that prove my point!".  I have the training to debunk their nonsense, but the vast majority don't.  how many crap medical studies come out each year due to bad statistical methods combined with FDA corruption?  this has a much bigger impact on the average person's life than religious nuts spouting off.  The authority of the FDA and pharmas derives from their panels of scientific experts.
