I was raised Quaker as well and still consider myself culturally Quaker, though I'm atheist and attend Meeting mostly only at weddings or funerals at this point.

What I value most about Quakerism is the emphasis on absolute honesty.

My father took time off college to protest the war -- which war, I'm not certain. He found himself questioning whether pacifism was truly his belief or something he was brought up with. So he enlisted to try out the other side. He didn't actually fight, but was trained as an artillery surveyor. When his superiors suggested he go to officer training school he asked for some time off to think about it, then came back three days later having decided he wanted to finish college and become a psychiatrist. He met my mom at his Quaker college, went back to Meeting, and some years later became a psychiatrist (and died shortly thereafter, not from the psychiatry). I've always thought it was cool that he tested his beliefs like that. His wider family was a bit uneasy with his choices but respected his process.
