To me the billboard appears intentionally inflammatory. From the perspective of the average viewer, it shows the words slavery, masters, a bible quote and what appears to be a shackled African man. The ability to interpret what this really means in regards to atheism is simply beyond the grasp of many, who will only view it as racist.
The discussion seems to degenerate into a question of racism and the intended message is lost in the noise. It seems to me that the message of atheism and secularism becomes unfocused with this kind of approach.
