The implication is if you suspect widespread conspiracy, you will hinder efforts to make systemic and institutional changes.

It's like a doctor saying you shouldn't worry about how far
the cancer has spread, you should just focus on changing your diet and exercise habits. Well some times you need to know how far the cancer has spread in order to know what to do about it. Sometimes the cancer has gotten so bad it requires immediate drastic measures.

Granted some people will become overly agitated when they hear it is cancer
like people who become overly paranoid about government conspiracies. But I contend many, probably most here on this board who question the official story of 911 are not overly paranoid - they've seen some evidence that
implies a huge problem and they want some real thorough testing done. This doesn't preclude anyone from making systemic changes.
