Ultimately, the reason why people deny obvious facts like climate change, evolution, the Holocaust, and the like, is because they don't trust the experts. Tell me, do anyone of you know from first hand experience that those things exist? You haven't seen the Holocaust happen. You did not go and visit the gas chambers. You did not read first hand the diaries and records of the Nazis. What you know about the Holocaust has been presented to you by historians. That's all fine if you trust the historians that they aren't making it up or distorting the fact, but if you think they have ulterior motives, then it is a logical conclusion that whatever they spend so much effort presenting to you, must be something that they want you to believe but is not exactly true.
The same argument for climate change: none of you are actually climatologists, and while you list research showing anthropogenic climate change, you did not actually do the data analysis or the models yourself and you are trusting the climatologists, like the IPCC, to have shown the truth. But you entirely discredit these organizations, then the logic follows that whatever they produce is discredited and thus climate change has nothing to do with man.
To an outsider that trusts that the science is correct, this distrust of what seems to be an overwhelming consensus is bogus. But from the average, non-financially interested denier's angle, that 'consensus' might as well have been made by the Illuminati.
I hope I have shed some light onto BOG's intransigence.
