Bill Maher's take on world religion in his documentary titled Religulous
(Religion + Ridiculous) is, to put it simply, looking at the core of world religions and finding flaws in them. Maher says that to have faith is to give in. Instead, we should doubt and question every thing.
The only appropriate attitude for man to have about the big questions is not the arrogant certitude that is the hallmark of religion, but doubt. Doubt is humble, and that's what man needs to be, considering that human history is just a litany of getting shit dead wrong. This is why rational people, anti-religionists, must end their timidity and come out of the closet and assert themselves. And those who consider themselves only moderately religious really need to look in the mirror and realize that the solace and comfort that religion brings you comes at a horrible price.
With the last sentence, Maher takes an extreme attitude towards religion. According to him, religion in any form is dangerous as it answers unanswered questions and gives power in the hands of people we don't want power given to.
