We're aware of all their careers. They're widely published since the astronauts were celebrities of sorts.
How exactly does that translate into them being liars "by definition"? You're going to have to explain that.
The fact that you assume we're not familiar with their careers speaks volumes about how it came to be that you went down the road of ignorance. You, like most HBs, assume we only have a very superficial knowledge of Apollo topic. You think that going a little deeper, you'll stun us with the technical detail. Like most HBs, you're wrong. We know more about it than you could ever imagine.
That you thought we wouldn't know something as obvious as the careers of the astronauts is laughable.
