Atheism (especially in America) is often labeled as angry. It seems to be hinted that beauty and poetry stem from other (perhaps more "spiritual") ways of living.
I can appreciate the culture expressed through the ages that can be attributed to the passion of people inspired by their belief in things beyond themselves and their lives, as Dawkins says "Cultural Christianity".
However, in writing music I have found atheism a very rich source to draw upon for inspiration. My own personal musical preferences and writing style have lent themselves to a somewhat aggressive sound. If you're interested in hearing what I mean I can link you to a sample: (Excuse the poor quality of youtube's compression.)
I suppose I am wondering if anyone knows of other music artists that do, or have, specifically drawn on atheistic inspiration? I am wondering if they tend to be more aggressive or if there are some who express the beauty that does exist within it?
