Conspiracy deathmatch

I realized recently that, in the best tradition of fighting fire with fire, it’s possible to counter some conspiracy theories by invoking other conspiracy theories. The best two examples I’ve come up with so far are as follows:

• The anti-vaccination movement is just an Illuminati plot to thin the ranks of the masses via the resurgence of preventable disease! The same is probably also true of the persistent cancer-hoax myth that encourages people to forego conventional treatment. Don’t let the Illuminati win – vaccinate, sheeple!
• Of course the moon landing was real! NASA got there by secretly translating and implementing the wisdom left to us by ancient aliens in the form of Egyptian hieroglyphics, duh. All attempts to convince people that the moon landing was faked are actually designed to prevent us from learning the truth about these mysterious beings and their other technological gifts to us, which are currently being kept from the public by NASA and other government agencies.

These are the best matches I could come up with, but there must be other effective pairings out there too. Add yours in the comments!
