I know how badly you'd like that to be true but there are a couple of points to make. First of all, I don't know of a single case of someone slaughtering their neighbors, en mass, in the name of atheism. Atheism isn't a cause or an agenda, it's a lack of superstition in one's life.
Secondly, atheists don't claim to be more moral than everyone else so when they murder, unlike with christians, they are equally immoral but aren't being giant hypocrites.
Thirdly, because atheists are a small minority of this planet, to call them "equally willing" is a false equivalency. The faithful, as is well demonstrated in the middle east and elsewhere, have no rational boundaries for their thoughts and, thus, their actions. For an atheist to make the argument that it is proper to strap a bomb to his chest and blow up a crowd full of women and children is unthinkable. The faithful, however, who possess no intellectual standards for their thoughts and behaviors, are, thus, free to do absolutely ANYTHING to anyone. Therefore, the murderous potential of theists is, as evidenced by news reports, limitless.
