There's been a bit of a reaction against the constant anti-religious bashing on Reddit lately and I don't think that it's any less secular than it used to be. I think people just eventually get tired of hearing the same arguments repeated over-and-over against, with less intelligence and less wit each time. I think that people here realize the problems that a religious debate can lead to, and so avoid them.
The problem appeared when the /atheism/ subreddit became one of the defaults. Some of the /atheists/ aren't in it for discussion, they're there for blind antireligion. When that turned mainstream it pissed a lot of people off.
