As a non-militant atheist of long standing, I don't believe atheism is "for" anything. It is the logical outcome of not being able to believe in extra-human forces that take a personal interest in our individual lives and whom we should appease in the hope of a better life or afterlife. Apart from anything else, the sheer bureaucracy inherent in the Christian structure of heaven and hell, and who gets sent where, has always beggared belief!
I have no interest in analysing how religion works except as part of the, to me, more important analysis of how extremists manipulate religion for their own ends.
And I can't see the point of a thread devoted to atheism unless it is to be a vehicle for the religious and spiritual to argue against it: a sort of religion and spirituality thread in reverse.
This is longer than my usual contributions to GN, but I am sitting in DD's house waiting for a furniture delivery. This requires the patience of a saint. Oops, what have I said?
