""Why does it concern atheists so much?""

Simple Ake! It doesn't, until some religious evangelist starts multiple threads to attack them.

Not one of the non believers would have bothered to start anything, had JtS not got a bug up his arse about "militant Atheism", an oxymoron.

If you attack anyone and he fights back, that does not make him a militant, the term applies much more aptly to you!
