"I guess the bottom line is that I believe that man, on an individual level, is a noble creature; ...and most others buy into William Golding's man."
I certainly think he can be, and many have been, and at a very local level I think, perhaps, even many are.
"These conspirators know most of the public are conditioned to succumb to their declarations as the so called authorities and/or experts."
And this is the crux of the problem as I see it. I don't necessarily think 'man' (the overarching) is evil, I just think man tends toward the lazy and, perhaps, even narcissistic. And because of that, a few (bad, evil, power mongering, take your pick) men (used as a pronoun for all sexes) will always attempt to compromise the many, and many of the many will easily be compromised (and some ignorantly, but gladly so).
The issue goes far beyond the carbon flame war. It's present it most of what goes on in 'life' today at a macro level. I think your view that 'we can all just get along' is a bit Pollyannaish. There will always be those who want to control others.
"Mankind can continue to survive if he is allowed to live by his own rational thinking."
I think I would change this to say "if only he would begin to think critically about the world around him, and reacted rationally, in his own best interests."
