Mike, you and Ready miss the point.

Governments - and particularly the US Government CANNOT BE TRUSTED - and therefore ANYTHING and I mean absolutely ANYTHING you posit against them must be true!

So if we say that cancer is a plot by our government to eradicate humans so their overlords from Dimension Q can take over the planet and despoil our resources, and then if you doubt this, you are either 1) a government plant or 2) just plain gullible.

Now bend over and prepare for assimilation.
