Just an anecdote on this, a few years ago (in a university town in the US) I was in a bookstore and overheard a small group discussing what sounded a lot like New Atheism. What stood out to me was one of them arguing passionately for greater group solidarity, saying that they shouldn't squabble over whether they call themselves secular humanists or atheists or whatever. So these people are still out there. Of course, in this same town social justice activism is much more prevalent, and there was something pitiable about this group, as though they knew that their brand of politics isn't in favor anymore. But I was struck by how strongly some of them still wanted to change that. I'm not an atheist, but I think groups like this can provide a healthy counterbalance to the kind of fervor being discussed here.
