Representative Pete Stark (D-CA) has publicly confirmed that he is an atheist, thereby become the first openly atheist member of Congress in American history (hat tip: Radley Balko).
However welcome, Stark's announcement is not much of a counterexample to my argument that atheists are severely discriminated against in the political arena (see here and here). Stark is a well-entrenched incumbent in a heavily Democratic district and is probably nearing the end of his career (he is 75 years old). He therefore is running a much smaller political risk than would most other politicians if they made a similar statement. Although Stark's announcement has some symbolic value, this small step for an atheist is also a pretty small step for atheist-kind.
