MSNBC contributor Pat Buchanan has made a career out of bigotry. His thoughtful contributions include calling gays satanists, praising the Nazis and the KKK, decrying Dr. Martin Luther King as a fraud, and telling African Americans that they should be grateful for slavery. While touring the networks to promote his latest book, Suicide of a Superpower: Will America Survive to 2025?, he stopped by a white nationalist radio program The Political Cesspool which was only too happy to advertise his theories. In response, African-American civil rights organization ColorOfChange.org and CREDO Action gathered 275,000 people who are demanding that MSNBC President Phil Griffin fire Buchanan immediately. The ColorOfChange.org petition reads, “Buchanan has a long and consistent history of peddling white supremacist ideology as legitimate political commentary, on your network and elsewhere.” Noting that Buchanan has the right to express his views, the petition says “he’s not entitled to a platform that lets him broadcast bigotry and hate to millions. If MSNBC and NBC want to be seen as trusted, mainstream sources of news and commentary, you need to fire Buchanan now.” Buchanan has not appeared on MSNBC since he began promoting his book on Oct. 22.
