That’s not conspiracy theory, that’s a legitimate question seeking truth. I’ll lay bare what the conspiracy theories are!
There is a fact or truth.
There is falsehood or fiction.
So, two sides here.
The falsehood or fiction cannot stand truth. So how do you make the falsehood look like truth?
The people on falsehood side float numerous theories with variations of truth, which is not truth, and make a strawman argument out of it to refute it to give an appearance of victory for falsehood. In this propaganda, they also count on the sheer volume of their theories to bury the truth. Thus, legitimate questions are evaded and truth suppressed.
Truth side asks legitimate question.
Falsehood side propagates conspiracy theory.
Not the other way!
Say there is 50% truth side and 50% falsehood side.
When such conspiracy theories, only to be later refuted, attack falsehood, it will pull in some believers from the truth side. Like enemy of enemy is a friend style followers. Say 60% of truth side fell far the conspiracy theories, and when refuted, they have no option but to accept their defeat. Thus truth side is weakened and is now reduced to 20% (50% - 60% of 50%). The 80% support is good enough for the falsehood side to carry on with their agenda.
