The case is simple. Its supporters who want to over complicate with fictitious claims.
Again an over simplification.
Supporters who work in 'echo chambers' are more prone to their unconscious bias leading them to interpret what they want to see from ambiguous evidence.
Not all supporters fit in to the above category but may at times stray in to it.
Some supporters have completely different theories.
Your blanket opinion and dismissal that
all supporter claims are fictitious is in part caused by your own rigid stance, which is based upon
some evidence from 1985.
It's you that chooses not to be more open minded. But you should understand that your choice to be closed minded can have absolutely no impact on the actual evidence itself.
