There was also political opposition. Sociobiology re-ignited the nature and nurture debate. Wilson was accused of racism, misogyny, and sympathy to eugenics. In one incident in November 1978, his lecture was attacked by the International Committee Against Racism, a front group of the Marxist Progressive Labor Party, where one member poured a pitcher of water on Wilson's head and chanted "Wilson, you're all wet" at an AAAS conference. Wilson later spoke of the incident as a source of pride: "I believe ... I was the only scientist in modern times to be physically attacked for an idea."
