Lori Lipman Brown is the first registered lobbyist in Washington for atheists. She is also the director of the Secular Coalition for America who is working towards a more widespread acceptance of atheists in today's culture. She represents the approximately 30 million Americans who don't believe in God or don't have a religious preference. Dislike for atheists is what often makes these non-believes afraid to "come out of the closet" and it is important for society to be more educated and accept widespread views that aren't similar to their own.
Though there is already lobbying taking place in attempt to further the separation of church and state, Lori is working on things such as "removing references to God from the citizenship oath". I think that this article is enlightening and I believe that atheists have as much of a right as another other group of people to express their concerns and be critical of legislation that might be disadvantageous to them.
