Concept of Religion in India and the rest of the world is different. In most of the Indian religion or originated from India the God is a matter of personal faith, not the society or system faith so you see people even create their own god based on their faith and society does not have any issue with it.
One more thing about religion in India is it's treated as a way of Life rather than driven by a divine book (though most of the Indian religion has divine books too) which allows people to remain respectful towards God even when someone does not believe in God.
Will love to see the others comment...
