I agree with hcour on this one. Simply believing something doesn't make it so, regardless of the zealotry of such belief. You are grasping at straws. Paranoid schizophrenics are convinced beyond all doubt that there are people plotting against them. Of course, that doesn't necessarily make it so.
As for things being believed simultaneously by people in large numbers, that does not validate a belief in and of itself. Much of the atrocity and genocide that has occurred throughout history was orchestrated by people in large numbers, including, but not limited to (by any means), the Crusades, Nazi Germany, Kosovo, Rwanda and so on. Mass hysteria and a uniform belief is not evidence of validity. It doesn't automatically make it right.
I continue to be astonished at the lengths people will go to justify what they believe in the absence of a scintilla of objective evidence. I do not think that you need to justify your belief, by any means. Your beliefs are your own, and you are entitled to them. But if you must go about justifying them, I urge you not to do so lamely. It is curious how intelligent people who are religious readily lower their standards when accepting evidence of a deity, whereas they would not accept such low order "evidence" in any other context unrelated to their religion. I think this phenomenon is identified as the "leap of faith." For skeptics such as myself, the chasm is just too great.
