Um.. America might be better with less fanatical religion. And I'm a Christian. But a lot of the policy/ideology of those who are very religious makes me hesitant to say that. Belief in Jesus should not be tied to a lot of the intolerance, greed, and archaic beliefs of religious areas.
Haven't you seen South Park? Once we get rid of religion we will all fight about science.. Praise be science... Or the Praise me, it really doesn't matter, because no matter what it is there will be people with opposite opinions on the matter.. Until all are one
If there's no religion, people will kill each other everyday, there will be no laws, no nations only tribe. We will never get modern.
Your stupid if you think there would be peace. Religion or not there will always be wars to be fought.
