There may be some interesting tangents, but ultimately, trying to counter conspiracy theories with facts becomes very tedious, not to mention a waste of time, because no matter how many facts are presented, the conspiracy theorist will take everything as further confirmation of whatever insanity s/he believes.
So one is left with a choice between spending time presenting facts, to no avail, or letting the idiocy stand uncountered. Frankly, it depresses me that at a time when so much information is so readily available, people still prefer to believe in absurdities than to become informed. It tells me that humans haven't progressed at all - we've just become more dangerous, because technology in the hands of primitive minds is a truly dangerous thing.
