That's a really charitable way of framing the fact that a 15% minority screeching about "the government would never" and "but there's no proof" was able to control the narrative despite people generally having doubt or believing otherwise privately right up until the point that the proof was public record and so ironclad that even mainstream media had to report on it.

(I assume the 85% number is made up, but for whatever the number is the point stands)
