When faced with overwhelming evidence that it is likely that man-made
influences are a large part of global warming, nob quotes discredited
'scientists' as his 'proof' that this is not the case.

When confronted with quotes from NASA that do not support his thesis,
nob just keeps repeating his mantra: "It isn't true; it isn't true."

What bizarre religion or belief system could be the basis of his
incredible whoppers in the face of hard evidence?

I think I have found the answer: nob is actually Dr. Joseph Goebbels.

"If you tell a lie big enough and keep repeating it, people will
eventually come to believe it."

"The most brilliant propagandist technique will yield no success
unless one fundamental principle is borne in mind constantly - it must
confine itself to a few points and repeat them over and over"

"Intellectual activity is a danger to the building of character"

--Joseph Goebbels

I think that nob must also have known John Stuart Mill. Where else
could this have come from?

"Conservatives are not necessarily stupid, but most stupid people are
conservatives."
--John Stuart Mill
