You can tell a lot about people by the conspiracy theories they subscribe to. From Patrick Armstrong at strategic-culture.org:
A deeply divided country: there is no common conversation in the United States today – one person’s conspiracy theory is another’s truth.
No subtlety of thought survives in the culture of unreason. Public space is populated with poseurs, cutouts, and imposters. Public discourse, with some exceptions, is much of the time not worth bothering with.
– Patrick Lawrence: Obituary for Russiagate.
There is a conspiracy theory that the CIA put the very expression into general use to discredit alternate theories about the murder of President Kennedy. Perhaps that’s true – there is a CIA document – but the expression has been around for a long time. At any event it has become a slur to discredit political opponents. The accusation replaces rational discussion.
There have been actual conspiracies in history. There was a conspiracy to murder Caesar. And to murder Anwar Sadat. The Bolsheviks did conspire to take power and so did Guy Fawkes. Sometimes they succeeded – often surprising the conspirators – and sometimes they didn’t. Many times the conspirators thought the deed itself was all that needed to be done but Caesar was succeeded by Caesar and Sadat by his chosen successor. There are probably fewer conspiracies than people imagine but they do exist.
Conspiracy theories abound in the USA today. But, it should be made clear from the outset of this discussion that there are two different kinds of conspiracy theories – unacceptable ones and acceptable ones. An example of the first kind is the assertion that Trump was cheated of victory by vote-faking in key areas. The assertion is “baseless”, pushed by the “far-right-wing” and the “deluded“; has been “debunked” in detail; its so-called arguments are “bogus, none credible“; there is “no evidence” and so on. The full weight of the corporate media stands against this idea and it flourishes only in the undergrowth. Nonetheless, 29% of Americans in a March survey “completely” or “mostly” agreed that the election had been stolen from Trump (66% of Republicans, 27% of independents and 4% (!) of Democrats). So that particular conspiracy theory has significant support.
