in a democracy everything will be chosen through elections, like it or not the demand of the majority will be the rule of the country. as I said you may like it or not, that's the meaning of democracy.
by your logic n#dists should be able to walk n@ked in western countries without being arrested by police. but it's not gonna happen, every society has a definition for a minimum clothes that you should use in public places, their actress play fully naked roles in movies, but the same actress has to wear her clothes when she appears in the society. why? because it's the people's demand, because people have the right to not see such a disgrace too, because it has become their law.
the same thing applys to Iran too, and our definition for minimum clothes is the Hijab.
you said current Iranian are less religious, well it's your imaginations, just look at the pre-revolution pictures and movies to see the opposite. a while ago I was in a hospital in the ceter of the town and from hundreds of women that I saw, the number of bad hijabs wouldn't reach the 10. the fact is that these bad hijabs which are mostly from the upper class families appear more in public and shopping malls, but it's just a false flag. also you go to small towns and villages and it's really hard to find some instances.
also even most of these bad Hijabs will disagree with your idea for a complete freedom in society.
and finally you said limitation would lead to wore scenarios, so may I ask why the number of crimes, the number of sexual harassment in western countries is bigger than Iran?
the fact is that human's sexu@l desire is endless, the more you see, you just become more addicted, more h@rny, so your plan for removing the limitations will lead to even worse scenarios, as it already has happened in western countries, and I guess you can find the statistics yourself.
