I've occasionally remarked that I don't care so much what people believe as I do how they act. The people I enjoy spending time with are not always those who share my beliefs, but are those who demonstrate integrity, respect, honesty, and other virtues. These virtues are associated with not just holding beliefs in the sense of a mere tendency to agree with a statement, but a deeper belief that actually has consequences for one's behavior. When I was a born-again Christian, I heard many sermons to the effect that many Christians were Christian in name only, paying only lip service to the doctrines while not living their lives in accordance with them. Clearly, there are a lot of such people out there.
(Read the rest, where I recycle an argument I originally wrote in a pamphlet called "Three Reductio Ad Absurdum Arguments Against Evangelical Christianity," at the Secular Outpost.)
