What constitutes a conspiracy theory ??

Is it any opinion that doesn't agree with mainstream thinking ? 

Does that include opinions of academically qualified people ? 

Or does it only apply to wild ideas from obvious tin foil hat wearers ??

And who,by chance invented such a phrase ?

It's anything that goes against or stops the MSM and big Pharma narrative being forced fed to the sheepeople. 

Edited from Wikipedia:

 

A conspiracy theory is an explanation of an event or situation that invokes a conspiracy by sinister and powerful actors, often political in motivation, when other explanations are more probable. Conspiracy theories resist falsification and are reinforced by circular reasoning: both evidence against the conspiracy and an absence of evidence for it are re-interpreted as evidence of its truth, whereby the conspiracy becomes a matter of faith rather than something that can be proved or disproved.

Research suggests that conspiracist ideation—belief in conspiracy theories—can be psychologically harmful or pathological and that it is highly correlated with psychological projection, paranoia and Machiavellianism. 
 

hmnnnnn, perhaps Wikipedia are deliberately being critical because they don’t want us to know the truth.

It's just a label, often aimed to discredit an inconvenient truth.

You know it when you hear it. References to lizard people globalist masters is a typical giveaway.

FBI

to disparage those

questioning JFK / lone-shooter/ Warren report.

CIA, FBI, LBJ, Texas oil, Mafia, Military Industrial Complex

all hated the Kennedys.

Conspiracy theory was apparently a phrase coined by the CIA back in the 60s to ridicule any narrative that wasn't in line with the officially released one. Would say its been very successful, no doubt lizard aliens has helped that along...
