- Stark's atheist views break political taboo (San Francisco Chronicle, March 14th 2007)
- Humanists Praise Pete Stark for “Coming Out” as a Nontheist (American Humanist Association)
The following day, the American Humanist Association ran an advertisement in the Washington Post, congratulating Stark and identifying a number of other prominent humanists including their former honorary president Kurt Vonnegut (pdf).
Kurt Vonnegut died on April 11th, 2007.
With those selected facts, it would be easy to construct a superstitious explanation for Vonnegut's death. But Wikipedia identifies two other people who died on the same day as Vonnegut: Roscoe Lee Browne (son of a Baptist minister) and Ronald Speirs (US Army officer who is rumoured to have killed several German prisoners and one US sergeant). There is only one pattern here.
