I thinkhe's just a hack that doesn't care what he writes, damn the consequences.
It was a habit that eventually got him where he is today- nowhere.
The chemtrails hoax is hard for us normal people to understand because unless you can somehow 'understand' irrationality, it doesn't make sense. One way to look at it is in terms of evoltion, but backwards. Rather than favoring survival of the fittest, as in traditional evolution theory, the more rational people self-select away from it, while the more irrational people remain and fresh open minds continue to opt-in.
Once indeep enough, depending on whatever their preexisting belief systems and the amount of cognitive dissonance that may develop if they start to change, it can be very hard to back out. Someone like Thomas, for example, how does he back out now? His coping mechanism so far has been to just remain generally quiet, which has been aided by very few backers supporting him any more.
Carnicom has been relying more and more on the Morgellons folks, who are the few that are able to get past his failures to 'produce' anything of value for over a decade. Many others just turn to repeating the 'outrage-of-the-day' develped by others, sort of like Anthony Hilder does, while not sticking their necks out on anything original.
The ultimate fate of Michael J. Murphy might be like that, he has wide-ranging conspiracy theory ideas and some momemtum. A single issue person on chemtrails that comes out with stuff that is easily debunkable has no future, there is a limit to what people will put up with, especially when you claim "hospitals are jammed" as Thomas has for a decade when it's obvious they are not.
BTW, Michael J. Murphy has gone to Maui, it'll be interesting to see if he ever comes back.
