Perhaps people could talk about more important things. How often do people go to war over science? There are scientific debates, there are scientists that disagree about things, but they don't go to war over it. I'm not saying the world would be war free without religion, but it would be a much safer and more peaceful place. People claim religion gives people morals as they go and slaughter families in other countries simply because they disagree with them. We're "helping them" by forcing our religion on them.

Unfortunately, religion will never cease to exist.
