Don't believe in God? You're not alone.
This poster, produced for Students For Freethought at University of Wisconsin Stevens Point, was meant to demonstrate that it was okay for people to express religious opinions that didn't fit the norm. SFF itself doesn't advocate any specific position besides separation of church and state and the promotion of rational thinking.
Many people seemed to find this poster offensive. It was consistently removed by students that couldn't handle an opposing view, and was the first of our posters to be written on.
Eventually, when we walked around campus to do poster checks, we learned to check the garbage for our posters before actually checking the wall. Anytime we found a poster in the garbage we put it back up on the wall as is, wrinkles and everything. If we couldn't find the stolen poster we would try to replace it within the day.
This poster inspired us to create another set of posters encouraging people to write on them and share their views.
