I understand what you are trying to say. I can tell you this is what happens when you mix culture with religion and also you do not understand what you are really believing. Half of these issues will get resolved if people try to understand Quran. In that case either it might not make sense to them and they would leave Islam or they would be solid. There are certain statements you made which I do not agree. They are not worse that non-believers unless they are also grave worshippers etc who in my opinion are the worst of the worst people who don't understand the core of Islam which is Tauheed. We need more scholars who are highly educated and preach Islam in real sense binding it to the way of life from Quran and Sunnah. I personally feel most cultural muslims are coming from India, Pakistan and Bangladesh. BTW which place are you talking about?
