ELI5: Why are conspiracy theorists "nuts" when many conspiracies have been proven?

Many conspiracies have been proven true.  The bankers and NSA are probably the most recent ones to come out as true.  So why is it that, all conspiracy theorists are labeled as nuts?

*disclaimer*  I am in no way endorsing conspiracies.  Just curious as to why they are automatically crazy.

Confirmation bias.  Most conspiracies rely on belief (not evidence) based on a previous opinion.  Also, you don't remember the ones that are just amazingly wacky and untrue (and there are FAR more of those).  

Do you think we have tracking devices implanted in us?  Are the black helicopters out to get us?  Those are the popular wacky ones.

The conspiracy people also have this tenuous grasp on their perceived enemy.  When it applies to the government, they're both amazingly pinpoint accurate and diabolical, and unbelievably inept at the same time (which can't be the case).
