People should value truth and authenticity. It's far more valuable than attributing inaccuracies to persons or events simply to manipulate the emotions and aspirations of mankind. If I discovered that the Moon landing was falsified, I wouldn't simply continue with a lie, because it makes me feel better to believe we really achieved such a feat. I also don't think that the truth is something one should belittle as "random facts".

I'm sure this is an argument that people like Nixon would solidly support and probably did.

(Note, I'm not a Moon landing conspiracist -- it was just an example.)
