Well, it is a recognized psychological phenomenon, pdq, that people filter information through their established emotional prejudices, and on the basis of that they decide what is "hate propaganda" and what isn't, what is a "reliable source" and what isn't, and so on. As our prejudices in most political areas are diametrically opposite, I doubt that we well ever agree on much of anything. It works this way: You think the USA is a progressive force in the world, and is protecting the world. I think they're a fascist empire bent on world conquest and in the control of a criminally insane government that is about as bad as most such governments usually are...which is very bad. I also have no high opinion of most of the other governments which the USA seems to feel are in its way at the moment, but they are not nearly as dangerous as the USA is, because the USA does about 50% of the world's annual military spending and is in the habit of attacking other people anytime it wants to, even if they are incapable of attacking it. That's what fascist empires do, as a general rule.   

And so it goes. I still suggest you read that site on Iranian history...plenty of good info there, and I doubt that I would agree with all of it, so you may find something you like there.

What I quoted from was an article in The Guardian.
