As this thread illustrates, the few remaining hardcore denier cultists here are now only interesting as case studies in abnormal psychology. There's little reason to pay attention to them for any other reason. These are the kinds of personality disorders common to deniers. For your own amusement, you can classify each each individual denier here by their respective personality disorders (they usually have more than one.)
1. Paranoid ("Global warming is a hoax!")
2. Narcissistic ("After scanning a few blogs, I obviously know better than all the best minds on the planet who have spent a lifetime working on the topic, being I am incapable of error.")
3. Sociopathic ("Lying for the cause is justified! Death threats are justified! All my bad behavior is justified!")
4. Histrionic ("Pay attention to me me me me me!")
5. Schizotypal ("I refuse to leave my bunker, where I read conspiracy blogs all day long, explaining my detachment from reality.")
6. Anti-social ("I HATE YOU &#^#%^ DIRTY WARMERS!")
So what creates a denier cultist? One big factor is the echo chamber. Unlike normal people, deniers usually refuse to look at any sources outside of their cult echo chamber, auto-defining any such outside sources as invalid.
Climate Change Debate Fueled by ‘Echo Chambers,’ New Study Finds
Lewandowski put out this classic paper on how deniers are mentally predisposed to fall for wide range of conspiracy theories.
NASA Faked the Moon Landing—Therefore, (Climate) Science Is a Hoax
That paper inspired deranged conspiracy rage from deniers, thus proving its point and leading to the Recursive Fury paper.

That prompted deniers to go on a jihad against the publisher. The right-wing authoritarian mindset common to deniers is decribed by Altmeyer's classic paper "The Authoritarians".
