But what you can do instead is make a half-decent fake, then accuse other things of being fakes, accuse your own fake of being fake with softball arguments, fake evidence for the other side, and in general throw up a wall of noise and hope it benefits you (the underdog propagandist's way).

That the truth can be found doesn't mean you can convince people of the truth.
