Ah, see, I don't view atheism as a community or as a political movement. It's just a personal believe (or lack thereof). And I don't see any evidence that this has declined.
There is an atheist community no doubt about that. The bright movement was a good example and then followers of Dawkins, Harris Hitchen et all which roams places like Reddit are by every definition of that word a community with a shared amount of argument, interest and an idea of outside the community.
