Anti-theists know better that killing religious people is not the answer... In fact, as an anti-theist I feel sorry for them. There's so many indoctrination and people become so blind and refuse to believe where the evidence points, I can't blame them, they are brainwashed. A wise anti-theist will simply know that religion will fade away with time, and whoever denies it is going against the tide.
