The Dump Dobson coalition has purchased a full-page ad in the Chicago Tribune this Friday and will hold a press conference on Thursday. The ad quotes Dobson, who in 2004, claimed “homosexuals are not monogamous. They want to destroy the institution of marriage” and “destroy the earth.”

The group’s ad urges Hall of Fame CEO Bruce DuMont to rescind the honor or face a protest at the induction ceremony, which will take place in a Chicago hotel. On its website the Radio Hall of Fame addresses the controversy, writing that a “broadcaster’s political, social or religious views never are considered when deciding to include or exclude a candidate.”
