The Out Campaign is a public awareness initiative for freethought and atheism in the US. It was initiated by Robin Elisabeth Cornwell, and is endorsed by Richard Dawkins, a prominent atheist. The campaign aims to create more openness about being an atheist by providing a means by which atheists can identify themselves to others by displaying the movement's scarlet letter A, a scarlet colored capital "A" in the Zapfino typeface, and an allusion to the scarlet letter A worn by Hester Prynne after being convicted of adultery in Nathaniel Hawthorne's The Scarlet Letter. It encourages those who wish to be part of the campaign to come out and re-appropriate, in a humorous way, the social stigma that in some places persists against atheism, by branding themselves with a scarlet letter.
