I think we forget that Persia lost the war 1300 years ago to arab invaders whose main goal was to Islamize Iran. That was the end of the nation that Cyrus, the communicator of the first human rights law advocated. The Iran that some of us advocate here is a lost cause and does not exist. For a short period of time, Pahlavi dynasty, whether good or bad, tried to bring back a new version of the nation which would respect religious belief of both secular and Islamic, although the Islamic group still had an edge. 1979 took Iran back to where perhaps the majority want to be, an Islamic country. Majority in Iran put Islam first before anything else and thus an Islamic republic makes sense. it is about integrity, where it dictates that a muslim follows the book of Koran 100%. I dont believe there is a way to follow that, unless a government is in place to promote it. A corrupt government we say, but hey, show one government that is not corrupt. Thus Saudi Arabia and Iran are true Islamic governments who although corrupt as least implement the Islamic laws.
So, rightly so, the religious Iranians have celebrated Ashoora Tassoa for centuries at some point, after the 13th century invasion. To tell them to stop doing it in whichever way they like, is wrong, regardless of how uncivilized these photos would look to the other world.
Esmani and Fole have a point here, that by banning the actions, it will backfire. Rather, if a change of government towards secularism ever happens, which in Islamic world would not make sense, the number of these people would gradually decrease, if they are shown the light of humanity. Although, like any democratic country, areas would be allocated for these rituals.
Iran must go through the most fanatic Islamic system if it is to become a democratic secular country. The country is still way too religious. You would need alot more seculars to balance the power of the religious which is what you have in the western country. We saw the few years of religious becoming more popular in US and its effect.
Till then, reluctantly, we must allow the winners to enjoy the country they won many centuries ago as the changes they forced through centuries destroyed any chances of the existence of the nation Cyrus envisioned.
