If islam is spreading and the fastest growing religion, then why muslims find it difficult to live with other religions (in Kashmir, Chechnia, Palestine, South East Asian countries) and harash the minorities (in Pakistan, Iran, Afghanistan, Bangladesh). Definitely they feel insecure with other religion and know that their own muslims will convert to other religion.
If Islam is so good, why muslims kill each other in Iraq, Afghanistan and kill other people in Kashmir, Israel, US through terrorism.
These incidents clearly speak that Islam has created a fear among muslims against other religions and multi-culture.
Look you said, "A religion where you will find a separate god for every region / state / city this canot be a religion". You have a fear to live in a multi-culture society, adapt to different culture.
Read "Bhagwat Gita" and learn what is life, you will loose the fear and will love the universe.
Hindu religion tells "Basudheva Kutumbakam" i.e. the whole world is one family. Believe on this. Accept and convert to this religion.
