In recent years, Republicans and Democrats in the Iowa Legislature often agree on little. But they were nearly unanimous this spring in supporting an important piece of legislation — a bill requiring faculty and administrators at the state universities to go through training about the First Amendment and the rights it contains. Anyone skeptical of the need for the new law received a wake-up call last week when the U.S. Court of Appeals in St. Louis handed down a decision against the University of Iowa. The decision should embarrass and anger Iowans. In a blistering 3-0 ruling, the court said university administrators engaged in clear discrimination against a student religious group based solely on the views of the organization and its leaders.
