The evidence is the lack of contradictory examples
This sounds suspiciously like an argument from ignorance, Mick. Carl Sagan and that infamous one white crow may have a thought or two on this.
I've interacted with hundreds of chemtrailers. I've never found any that don't think there was a conspiracy behind JFK and 9/11. While not conclusive proof, it's a pretty big sample.
Agreed.
Of course you can never make 100% true statements about any group.
And yet you did precisely that, which is why I brought attention to it: "If you believe in chemtrails or 9/11 being controlled demolition, then you
automatically believe there was more than one shooter."
Had you said "the vast majority" or anything similar, I'd have no problem with it. But you went with the "automatically," italicized no less. Hard to express an absolute in more stark terms than that.
From your link:
Spurred in part by the growth of new media, conspiracism has become a major subcultural phenomenon.
"In part" suggests there were other factors involved as well. Some would point to increased access to previously inaccessible data and the attendant evidence that there was in fact instances to support the idea of a this or that conspiracy as being an important factor.
For instance, someone who believes that the American government was behind the 9/11 attacks is very likely to also believe that Princess Diana was deliberately assassinated. One proposed explanation for this connection is that beliefs in conspiracy theories somehow support one another (Goertzel, 1994).
A proposed explanation that ct's somehow support one another? Hard hitting, incisive stuff, that is. I think I hear their proposal for their next grant and the need for "further research" to iron out the kinks in the "somehow."
Even though the perpetrators may be different in each case, the
fact that one massive, sinister conspiracy could be successfully
executed in near-perfect secrecy suggests that many such plots
are possible.
Got loaded language and facile oversimplification, oh researchers? Sheesh.
Over time, the view of the world as a place ruled
by conspiracies can lead to conspiracy becoming the default
explanation for any given event—a unitary, closed-off worldview
in which beliefs come together in a mutually supportive
network known as a monological belief system
This is certainly a possibility for some and a probability for many. That said, a strong case can be made that everything after the dash applies equally to the debunking community. In fact, that's my thesis to a t.
