I see Science and Spirituality as two things that could function well together in some aspects, not two separate things.
Notice that I didn't say religion.
I'm for organized religion and all, as long as it creates a positive and healthy and loving organization. However people take their beliefs and use them as justification for intolerance; that's unacceptable.
I could never be friends with a "hardcore" Atheist who demeans believers and treats them like ignorant sheep, nor a "hardcore" theist who condemns Atheists as evil and treats them like scum.
Personally, I find myself to be spiritual sometimes, and doubting of everything the next. It's not a matter of what has been proven or what has been disproved. It's just how I feel with my life experiences and surroundings.
No one really knows everything, so I keep an open mind and change my philosophies/beliefs as I go.
