Just because you fill up a cup, doesn't mean it was filled with water, you can fill it up with piss, you can fill it up with acid, you fill it up with all sorts of things.
Same thing here, these were stupid, uneducated fools, who had their heads filled with shit, and they went into the cities, and made war and put Khomeini into power. So yes many were stupid, those that weren't stupid were ignorant, your distinctions are BULLSHIT!
You see the same thing in America today. The south and other areas which are not urbanized have larger populations of both stupid and ignorant people.
