If a lie is only printed often enough, it becomes a quasi-truth, and if such a truth is repeated often enough, it becomes an article of belief, a dogma, and men will die for it.
Isa Blagden
If a falsehood is propagated sufficiently, it eventually morphs into a pseudo-fact, and if this fabrication is reiterated enough times, it will become an accepted principle, an unquestioned belief, and people will fight for it.
