Why I post anti-religious posters

I see a few posts around - other blogs, Facebook, etc. - that suggest that atheists shouldn't feel the need to harangue others about their beliefs, that it's all a personal matter. But, for those of us living in the good old US of A, too often it's NOT just a personal matter as we have people in influential positions advocating for a religious state. Those of us NOT so committed need to fight back, to argue for a state of reason. That's why I post what I post.
