I was born and raised in a muslim country , so i had my share load of religious endoctrinment as well.
From my personal experience and judging from previous posts as well , I think some people, especially older generations take religion and religious matters too seriously. In my opinion , it should be more of a way of life as it teaches you some important values , than some worshiping fanaticism.
I mean , worshiping a god is all right , as it can help you reach peace of mind and as long as it's personal. But as we've seen many times in the past , some people will inevitably use religion to gain money and control over the masses, like tftp pointed out , and it even continues to these days (Saudi Arabia anyone?)
