The term "militant atheist" in my opinion, was created and used as a form of coercion. One of the most powerful forms of brainwashing involves creating enemies and insinuating some sort of battle. You see this all the time, particularity amongst the evangelical movement. Visit battlecry.com for example...
The technique of demonizing the enemy, can be taken literally in our case. We are, as far as a lot fundamentalist Christians are concerned, directly or indirectly working for Satan himself.

(The pay sucks btw)...
