content: Conspiracy theorists aren't open minded.  They're addle-headed.  Having an open mind does not mean believing every outrageous claim that comes your way because it agrees with your internal beliefs.  An open mind is skeptical of any claim without evidence, especially claims it is inclined to agree with.  An open mind is capable of changing its beliefs as a result of new evidence.  An irrational mind simply ignores evidence that disagrees with it's preconceived notions.
