Spirituality is fine but organized religion needs to go the way of the dinosaur.
I differentiate spirituality and religion, and consider myself both "spiritual" and non-believer. I believe that people should be allowed to believe whatever that they want to believe, unless they are harming or oppressing others. For example, if someone believes in a deity that's their own personal decision but if they try to force their beliefs (laws) on others, then trouble starts. Or when they start a war with religion as a justification.
On a side note, I believe that most wars are not caused (initiated) by religion, but mainly by power/resources. Religion is often used as a justification or excuse. Same with many other things.
