Sorry, I messed up breaking up the text so I will repost it.
News is not always a good source sadly. Many things have been in the news, but the truth has later came out. Let me give you an example. During the revolution, someone locked the doors of a Cinema in Iran (Cinema Rex) and put it to fire. Everyone inside it died and they could not escape. Everyone blamed it on the Shah. Years years years later, despite "general knowledge" as you say, and despite news saying it was the Shah, it was revealed that it was in fact Islamists loyal to Khomeini and his clan that set it on fire. The fire on Cinema Rex heavly fueled the revolution and increased anger.
But it's not only this. Throughout history, I am sure even you, I have seen things being general knowledge, history etc. and those who say it's otherwise they have been laughed at (you have probably read about the issue with the earth being round or flat, those who said it was round were humiliated and persecuted.)
Another thing is for example the number of SAVAK agents. Generally 'everyone' thought it was around 60,000. But the truth is that it was more arond 6,000 to 8,000. But hey, remember, winners write history and if someone tires to challange it, people like you quickly try to put them down without being open minded. How many have tried in the past to explain about Cinema Rex Fire but got put down quickly because "no way man, you dumb, it's general knowledge, news said it, everyone said it, my mother his dad and their brother..."
General knowledge does not mean that it has to be true.
Why I am saying this? I want people to know the truth of everything. There are people out there who wants to spread bullshit about matters, and it's not only about this issue but many other as well. The winners write history, and so they have decided to write a history to their own liking. And I think you have probably understood that I believe that some people in west see the Shah was a bad guy. Note I said some and note I said west, because between Iranians many, and increasing, today look back to those days and think their parents did a stupid mistake.
Animal farm should be for you and not for me. I am being critical and open minded, but you refuse to believe anything else other than what your media tells you. (actually - I don't want you to believe me, I want you to be open minded and study yourself. I want you to think that everything that is being said in this world by the loudest does not neccessarily have to be the truth).
