Being a typical Atheist cat (one that can't be herded) I don't feel so strong about neither the A nor the actual campaign itself in its current shape, but I am feeling strongly about spreading the message of Atheism. And I therefore reckon that the more A's that are around, the better.
Richard Dawkins & co have made a tremendous effort in pushing Atheism. Dawkins could probably have chosen to be just an uncontroversial professor in a dusty office with lots of books on biology, writing the occasional piece on the problems of Creationism. Instead, he has taken on the world religions with full force!
