As usual and true to form, you oversimplify every argument to fit your conclusions. Nothing new there.
No one denied the influence of religion in our society and culture. That is part of the woven fabric of Iranian culture and society. Islam has inherently shaped many aspects of our lives, mostly in a negative manner. Here is why your argument is totally flawed:
Firstly, what you are saying about the Iranian revolution is absolutely incorrect. People didn't pour to the streets to demand more islam in their lives. It is simply not true. The slogans chanted by millions were about freedom and independence, self-governing and social justice. Students, progressive and leftist all united toward that common goal. Blame islam all you want but it wasn't the religion that motivated the masses to go to demonstrations. Yes, there were elements of the islamists that also participated but the vast majority didn't even have a clue about what islam is and what an islamic government would do to their lives. Hijab and other crap came well after the Shah's departure, when Khomeini had absolute power.
