Academic freedom
Additionally, Gonzalez appeared in the controversial 2008 movie "". The American Association for the Advancement of Science describes the film as dishonest and divisive, aimed at introducing religious ideas into public school science classrooms, and the film is being used in private screenings to legislators as part of the Discovery Institute intelligent design campaign for Academic Freedom bills. "Expelled" portrays Gonzalez as a victim of religious discrimination and the Discovery Institute campaign asserts that his intelligent design writings should not have been considered in the review. However, Gonzales listed "The Privileged Planet" as part of his tenure review file. Dr. Gregory Tinkler of Iowa Citizens for Science stated that "Being a religious scientist is perfectly normal and acceptable, but scientists are supposed to be able to separate science from non-science, and good research from bad. Academic freedom protects a scientist's ability to do science, not to pass off a political or religious crusade as science."
