I see the conflict here. As usual, it comes back to the etymology.
Those who look for "leaders" in atheism see it much as Margaret Atwood-- atheism is a doctrine, and atheists are those who follow or subscribe to that doctrine. Those here, who are mostly not of that type, see anything institutional as a threat to the soft atheism position-- they don't WANT to think of atheism as an institution, because it is largely the instiutional nature of religions, specifically the christian one, that they so much dislike.
