Censorship leads to suspicion of the censor's motive and undermines trust

It's natural that people get suspicious when an important area of public concern is closed off from public debate.

That's the sign of a cover-up... when the establishment story can't defend itself against the truth, so it bans it.

It's not like this simple logic can be held from the public, so the perpetrators just hope people don't look beyond the facade they have created to intoxicate the public mind long enough to think deeply about the matter and realise they're being hoodwinked.
