It's argued by some that even if religion (specifically Christianity) is false, it still might be useful on occasion to some people. Certainly on the face of it, this might have some merit. Here's a story about a would-be Christian robber being turned from his evil act (still running away though) by the words of the Christian shop assistant [BBC News].
Once certainly has to admire the presence of mind and the calm resolve of Ms Nayara Goncalves, the shop assistant, and good for her, I say. She defused a very dangerous situation - OK, the gun was only a replica, but she wasn't to know that, and one gun attracts others, and these situations frequently end up messy in the USA.
So suppose an *atheist* robber comes face to face with an *atheist* shop assistant? What then? How could that situation be handled? I can't see how a lecture about The Blind Watchmaker or memes or the ahistoricity of the resurrection myth or speculation about the origins of life is going to cut the mustard - you need a soft yellow underbelly. In the case of the theist, that SYU is the meek and mild Jesus thingy, washed down with a bit of fire and brimstone, no doubt. The atheist's weak point is *where*, precisely?
