It's not that unusual, really, although there's a lot of quite heated discussion about it within the RSoF. Ha ha; major can of worms. I was raised in in Quaker meeting and am very much culturally a Quaker even if I don't have the capacity to accept the divinity of Jesus Christ or the existence of God-in-the-Usual-Sense.

I'm probably an atheist before I'm a Quaker. It hasn't caused me any major problems yet and I would be very sorry to leave meeting if it became a big issue.
