Ebert on Creationism
Roger Ebert went ballistic about the decision of several Southern science museums to pull some IMAX movies that mention evolution due to fear from the fundamentalists' crowd. In his article, Ebert demonstrates excellent understanding of science and evolution and what the whole controversy is all about. He even points his readers to the Talkorigins.com for further edification. Good for him. I always liked him - now I like him even more.
