I'm 'spiritual' and the question of a differing fundamental perception between me and atheists is an interesting one. However, as humans, we often find ways to divide each other. To me, the most important aspect would be an open-mind, compassion, and a lack of extremism (ie hating or having contempt towards those who are different).
@Levin Yeah this is what I would find as requirement for my friendships, but not sufficient at all for long term partners anyway, probably because I expect a deeper sharing and connection and not just "someone who can be good for the future I imagine to build", also because I've no plans for that (thus no hurry, neither needing to get compromises).
