Take a look in the Turkey for example.An account manager in the company I work told once he observed that many muslims drink alcohol when its dark.People love spoiling Muslims name
The Motto: When its dark allah wont see it anyways
Anyways, those people are not really Muslims, because we have to believe that Allah is everywhereThose people are stupid!
If they believe in God then how can they think that they can hide from their creator???
Were u speaking about insane people????
I even guess young people in Iran have other sorrows than only religion. I think thats the inner fight between Muslims: The one who want modern religion and modern dogmas and other want to stay traditional.
The catholic church has this problem too. Many priests and even cardinals want a modern dogma because people leave the faith and the church because they are too much traditional, but the pope dont want, because he has enough people in Africa, Latin Americas and Middle Americas.
In the 60s and later again they had official reformes, because the priests e.g. still spoke in latin until then.
The Islam will need something like this earlier or later, but I fear anytime you will have your 30 years of war like Christians had in 15th century.
In general you can say: The better the life circumstances and the more prosperity you have in a country the more efford you need to held people in a traditional religion and its rituals.
You can see it in all western countries since about 40 years. If many muslims countries wouldnt have a dictatorship you won´t find the same religion there (e.g. Abu Dhabi, Tunesia).
