Summary
Look, I happen to have a very high opinion of Iranians and Iranian society. I think you are one of the most sophisticated people in the world (though, note, sophisticated and sophism share the same root ;). I think the Ayatollahs have, in many ways, perverted Iranian society (in others ways ensured it's independence). But your statement is too simple, too lacking in nuance. It is, frankly, dangerous (but I'll defend your right to share them with my life!) in the same way that statements about Iraqi's perception of America were 20 years ago.
Long Version:
"I was born and grown up in Iran "
I figured, but I didn't want to bring it up; if you're going to talk about "lived experiences" then it's fair that I ask you what your social class you belong to in Iran. Were you the son/daughter of an engineer? Or were you the child of a manual laborer? Did you grow up in Tehran, or Shiraz? Or did you grow up in a small village in the middle of nowhere? Did you have foreign DVDs when you grew up?
More succinctly, did your class make or was it depicted in "Children of Heaven"? (deserved the Oscar, btw. It was brilliant)
"First, a massive portion of the population (middle and upper class) are also considerable"
Well, doesn't that implies that the Ayatollahs did well by Iran? In the times of the Shah the middle class was proportionally small, certainly not large enough to make OP's comment wrong. (The answer is no, the Ayatollahs were a disaster and Iran's middle class, even if it numbers in the millions, is still a small fraction of the total population)
" and they _dont_ hate America."
OK, here I'll concede you're probably partially right but only because "America" is very ill defined. How can someone "hate" Akron OH? You can despise them, but hate? Ohioans are the nicest people I've met in the world (lived experience from growing up in four continents)! But, typically, when ppl talk about hating "America" they are referring to DC and DC's policies.
