Attitude: I generally don't care unless they try to tell me what to do based on their religion. This is generally never a problem, I've had more vegans and environmentalists bother me.
Getting along: we have some high faith denomination of Christianity here. I've worked with a few and generally don't notice unless they drop something heavy on their foot and don't swear.
Thought of believing: not since I was 12 or something.
Do not like faiths: I acknowledge they can create a sense of community and belonging. I have a dim view of the dogma that tends to come with them.
