Here's the point. Atheists, first of all, are not "militant." Flying banners from planes is not militant. Flying planes into buildings is militant.
Atheists are, however, tired of being distrusted and dismissed as without morals. Despite what you believe, one does not need a belief in a God to be ethical and moral. The whole "without God there are no absolutes" thing needs to stop. Atheists and religious folks are equally able to understand that morality is based on treating other justly. The Golden Rule is a good place to start, and the Christian Bible doesn't have a corner on that concept. It's sad that people would rather vote for a crooked religious candidate than an honest, hard-working person who admits to being an atheist. Why should it matter? Cripes, you even have a Bible verse that says that no good can ever come from a nonbeliever. Wow, I guess every time I've ever worked hard, acted with kindness, or helped a stranger it's been a self-serving act of evil.
We also do not love and worship Satan. We don't believe in him, despite your insistence.
So why do some atheists feel the need to speak out? Well, when people claim that all laws need to be Bible-based, we get a little uncomfortable. That really rubs the Constitution the wrong way.
