Didn't see this until now -- "Room for Debate" at the New York Times, with Rhys Southan weighing in interestingly (as usual).
Elsewhere in vegan-world, Gary Francione has an interesting, long essay about moral realism and "new atheism". It bothers him, as it does me, that new atheists often accept the following equation: ETHICS minus RELIGION = THIN GRUEL. In academic ethics, that equation is usually rejected. Generally, new atheists think giving up God makes a much bigger difference to everything than it really does. A prime example of the "huge difference" view (perhaps we should talk about "huge difference atheism" rather than "new atheism") is Alex Rosenberg's book The Atheist's Guide to Reality: Enjoying Life without Illusions, which I'm reviewing in an upcoming issue of Free Inquiry. This is HD Atheism cubed. My 2,000 word review, reduced to one word, would be "no". More on that when the review comes out.
