Interesting poll Android.
I would have to answer several of those though I would say. I think mostly, conspiracies are disinformation, hot air, the ramblings of various insane nuts and fear mongering. On top of the alien/conspiratorial stuff, there is the pseudo scientific and new religious material to wade through and the various charlatans and profiteers that head such groups.
It is indeed big business. Just look at how many ads are stuffed all around ATS..they are everywhere. Additionally, people in this business who are offering the truth by and large want you to pay for it which is of course a nonsense. There is a huge ammount of information to wade through before one can find the golden nuggets of information that may hold some truth.
While there is some value in this material I am very much moving away from my several year flirtation with it and am concentrating now on practical issues, ie, how to live outside of the system, ie, banking, electrical, foods, etc. A lot of the stuff being thrown about presently serves only to distract, induce fear and to confuse and I think the truth is so much more simple and currency free. If anybody tells you otherwise you are being ripped off. I think much of the material on alienism and channeled ETs is ludicrous and patently untrue as is much of the material surrounding 2012.
So whilst some of the material is interesting im rather bored of it now and want to focus on practicalities, earth mysteries and a reconnect with nature. Its free, its beautiful and its simple. And..you dont have to pay a subscription....
But yes, intersting question Android and thanks for posting it.
