I highly doubt that.
It isn't some random coming up to you telling you you haven't been.
It is someone that is repeatedly claiming it is all a lie and you are in on it.
They were under a strain, a strain of going to space, living in cramped quarters, no gravity and so on.
Clap trap.
Just like the silly actors and actresses under severe strain on the fake ISS showing us how to brush our teeth and crap or piss into suction toilets and all the rest of the fun games they play, like chasing people in Gorilla suits, etc, etc, etc, etc, etc, etc, etc.
Don't give me all this strain crap.
The only strain those people were under is the strain of keeping up a pathetic ruse after realising that they will have to live out their entire lives facing the public and reeling off utter nonsense, then just waiting for the day when people start to realise what their game was.
In a small way (for some) I have some sympathy with the actornoughts, because they were probably coaxed into doing something under a guise of fooling the enemy and got too far into it before realising the long term implications of trying to keep this nonsense up.
I'm serious when I say I feel sorry for some of them. I put myself in that position and wonder how I would react when I realise I have to spend the rest of my life telling the same fictional story, time and time again.
No wonder a lot of them went into recluse mode.
It's a bit different today because the actors and actresses are basically paid to do what all actors and actresses do. They play out any and all fantasies for a living and spend much of their entire lives on set doing just that, in any scenario bestowed upon them.
They don't really need scruples because their lives are scripted out for them and their existence if based on careful planning.
Stick to it and you live off the trappings. Go against it and you can be rendered a down and out nut case in a matter of weeks.
