Freedom From Religion Foundation

...Keep in mind this isn’t an “atheist club” for Congress. This is just a group dedicated to promoting reason-based public policy, keeping church and state separate, opposing discrimination against non-religious people, and championing freedom of thought around the world. In other words, there’s no reason anyone should be against this, including religious politicians. That won’t stop the complaints, but it also means the number will surely grow, especially in a future administration where evidence and science aren’t dirty words.
