I do not get your point.
You are saying people voted for IR due to freedom and economical reasons; and days later they did protest some of its policy like hijab.
In this case people then did not know the islam well or they were too much desperate and ignored The Islam, instead they focused on those reasons ; therefore did not take everything into consideration; but today people know Islam well; but this time they claim Hijab wearing must be by free choice.
If it is too complicated, then i write it agian another way:
what is the function of the Islam before Republic? When you say IR; what is it you are trying to tell?
when 98% voted to IR. it means they had different opinions. some for islam, some for economic reasons, some fo political issues and ...
as i said people thought in IR all people are free. but after revolution they faced with such rules and they protested against it.
people knew what islam is.but not about when it's in power. they were hearing only what khomeini was promise about how much IR will be good. and every one will be free. so people thought in IR system all are free, only a few one had doubt about those words of khomeini.
the differences between islamic republic with just a republic , in IR they officially share islamic ideology, they pay money to Islamic organizations to spread Islamic thought, do Islamic activities in the society.
the courts judge on Islamic orders.
stop westernize the country.
For a Muslim, an IR system without forcing people to do some stupid rules is the best choice, isn't it? a system that beside spreading Islamic thoughts officially, respect to freedom of all opinions and people.
no one thought when mullahs take power, they will force people to do such stupid rules. even khomeini supposed to go back to qom and doesnt interfere in politic anymore, but everything got changed.
mullahs always were supporting people against
tyrants, foreigners and ... they had a very good face among people.
at first people were not familiar well with definition of Islamic republic, they were just rely on Khomeini words.
after revolution mullahs start interfering in politic and day by day they moved to eliminate others and forget all their words that said before revolution about freedom.
but today there is a definition for IR, they believe in Republican principles if it's not against Islamic principles. islamic principles( their view of islam and their personal opinions) are ahead of Republican principles.
but it also doesnt mean they should force people to wear hijab, it's a personal order like namaz by Qur'an not a social order.
