Everyone has their own ideas on that.
For most people like me (atheist), it's about how religious they are..
Spiritual is cool, but someone devoted to an organized religion is just going to end one way or another. Been there, done that. Tried to avoid the topic like an elephant in the room, but it's always there and no matter how much you like someone and try not to address it.... No one will change the others mind, and it's an important topic for both parties... So in a nutshell... If they're a part of an "organized" religion.. NO.

yup.. I like coffee too. =)
